Add a wrapper around ar calls for native/cross recipes. This wrapper adds
the -D option so that deterministic archives are built for native/cross
output. This improves the changes of hash equivalence matches and hence
build artefact reuse.
We don't need this in the target case since we compile binutils-cross
with an option making this the default. We need a wrapper since we need
to remove the "u" option and replace it with "D" but also allow things like
"--version" to continue to work too.

All the users of the cross class I could find redefine the do_install
function. It is unusual and likely undesirable for the class to be
changing this from the default and likely a leftover from different
times. Remove it as it isn't doing anything.

As Alex Kanavin found, dependencies aren't always populated, particularly
with the hash equivalence server enabled locally:
'bitbake core-image-minimal' with gtk+ disabled.
can confirm with: $ tmp/work/x86_64-linux/qemu-helper-native/1.0-r1/recipe-sysroot-native/usr/bin/qemu-system-x86_64 -display gtk
qemu-system-x86_64: Display 'gtk' is not available.
Enable gtk in local.conf with: PACKAGECONFIG_append_pn-qemu-system-native = " gtk+"
'bitbake core-image-minimal', without deleting tmp/
$ tmp/work/x86_64-linux/qemu-helper-native/1.0-r1/recipe-sysroot-native/usr/bin/qemu-system-x86_64 -display gtk
qemu-system-x86_64: Display 'gtk' is not available.
This change ensures the dependencies are correctly handled as the full
sysroot is always depended upon even if things come from sstate.

BUILD_* flags can't be used as TARGET_* flags even for "cross" packages.
gcc-cross buils leaks config.log's through "gcc-stashed-builddir" and
TARGET_* flags to libgcc cross-build through "gcc/libgcc.mvars" file
on "gcc-stashed-builddir". This means that if BUILD_CFLAGS contains
host-specific flags like "-isystem/usr/include" libgcc build will
fail "do_qa_configure" and "do_package_qa" checks.
Remove host-related flags from TARGET_* flags for gcc-cross build.

Some TARGET_* flags are being exported in bitbake.conf currently, so
they are impacting all the tasks of a cross recipe even they are not
in use at all.
This can lead a lot of churn when the cross sysroot are shared by
machines while they have defined different TARGET_* flags.
And sometimes it even causes "Taskhash mismatch" errors.
Fix it by overriding with BUILD_* flags.

For this we move them out of the python section so they can be
overridden on a per-recipe basis.
The motivation for this change is that not all tool chains need the
path modifications provided by the command, and these will provide
alternative or empty commands. The Go compiler is such an example.

Mixing PACKAGE_ARCH with BUILD_* has always seemed somewhat odd. This
comes into play when building different SDKMACHINES as the PN space
for the recipes did once overlap. With the modern build process we
use, this overlap is a thing of the past since PN has SDK_SYS appended
to it.
cross.bbclass sets PACKAGE_ARCH == BUILD_ARCH so this change only affects
crosssdk.bbclass where PACKAGE_ARCH == SDK_ARCH.
The current structure is quite confusing and this removes this artefact
of history, allowing other gcc cleanups rather than meaning we futher
complicate the code.

This patch is comparatively large and invasive. It does only do one thing, switching the
system to build using recipe specific sysroots and where changes could be isolated from it,
that has been done.
With the current single sysroot approach, its possible for software to find things which
aren't in their dependencies. This leads to a determinism problem and is a growing issue in
several of the market segments where OE makes sense. The way to solve this problem for OE is
to have seperate sysroots for each recipe and these will only contain the dependencies for
that recipe.
Its worth noting that this is not task specific sysroots and that OE's dependencies do vary
enormously by task. This did result in some implementation challenges. There is nothing stopping
the implementation of task specific sysroots at some later point based on this work but
that as deemed a bridge too far right now.
Implementation details:
* Rather than installing the sysroot artefacts into a combined sysroots, they are now placed in
TMPDIR/sysroot-components/PACKAGE_ARCH/PN.
* WORKDIR/recipe-sysroot and WORKDIR/recipe-sysroot-native are built by hardlinking in files
from the sysroot-component trees. These new directories are known as RECIPE_SYSROOT and
RECIPE_SYSROOT_NATIVE.
* This construction is primarily done by a new do_prepare_recipe_sysroot task which runs
before do_configure and consists of a call to the extend_recipe_sysroot function.
* Other tasks need things in the sysroot before/after this, e.g. do_patch needs quilt-native
and do_package_write_deb needs dpkg-native. The code therefore inspects the dependencies
for each task and adds extend_recipe_sysroot as a prefunc if it has populate_sysroot
dependencies.
* We have to do a search/replace 'fixme' operation on the files installed into the sysroot to
change hardcoded paths into the correct ones. We create a fixmepath file in the component
directory which lists the files which need this operation.
* Some files have "postinstall" commands which need to run against them, e.g. gdk-pixbuf each
time a new loader is added. These are handled by adding files in bindir with the name
prefixed by "postinst-" and are run in each sysroot as its created if they're present.
This did mean most sstate postinstalls have to be rewritten but there shouldn't be many of them.
* Since a recipe can have multiple tasks and these tasks can run against each other at the same
time we have to have a lock when we perform write operations against the sysroot. We also have
to maintain manifests of what we install against a task checksum of the dependency. If the
checksum changes, we remove its files and then add the new ones.
* The autotools logic for filtering the view of m4 files is no longer needed (and was the model
for the way extend_recipe_sysroot works).
* For autotools, we used to build a combined m4 macros directory which had both the native and
target m4 files. We can no longer do this so we use the target sysroot as the default and add
the native sysroot as an extra backup include path. If we don't do this, we'd have to build
target pkg-config before we could built anything using pkg-config for example (ditto gettext).
Such dependencies would be painful so we haven't required that.
* PKDDATA_DIR was moved out the sysroot and works as before using sstate to build a hybrid copy
for each machine. The paths therefore changed, the behaviour did not.
* The ccache class had to be reworked to function with rss.
* The TCBOOTSTRAP sysroot for compiler bootstrap is no longer needed but the -initial data
does have to be filtered out from the main recipe sysroots. Putting "-initial" in a normal
recipe name therefore remains a bad idea.
* The logic in insane needed tweaks to deal with the new path layout, as did the debug source
file extraction code in package.bbclass.
* The logic in sstate.bbclass had to be rewritten since it previously only performed search and
replace on extracted sstate and we now need this to happen even if the compiled path was
"correct". This in theory could cause a mild performance issue but since the sysroot data
was the main data that needed this and we'd have to do it there regardless with rss, I've opted
just to change the way the class for everything. The built output used to build the sstate output
is now retained and installed rather than deleted.
* The search and replace logic used in sstate objects also seemed weak/incorrect and didn't hold
up against testing. This has been rewritten too. There are some assumptions made about paths, we
save the 'proper' search and replace operations to fixmepath.cmd but then ignore this. What is
here works but is a little hardcoded and an area for future improvement.
* In order to work with eSDK we need a way to build something that looks like the old style sysroot.
"bitbake build-sysroots" will construct such a sysroot based on everything in the components
directory that matches the current MACHINE. It will allow transition of external tools and can
built target or native variants or both. It also supports a clean task. I'd suggest not relying on
this for anything other than transitional purposes though. To see XXX in that sysroot, you'd have
to have built that in a previous bitbake invocation.
* pseudo is run out of its components directory. This is fine as its statically linked.
* The hacks for wayland to see allarch dependencies in the multilib case are no longer needed
and can be dropped.
* wic needed more extensive changes to work with rss and the fixes are in a separate commit series
* Various oe-selftest tweaks were needed since tests did assume the location to binaries and the
combined sysroot in several cases.
* Most missing dependencies this work found have been sent out as separate patches as they were found
but a few tweaks are still included here.
* A late addition is that extend_recipe_sysroot became multilib aware and able to populate multilib
sysroots. I had hoped not to have to add that complexity but the meta-environment recipe forced my
hand. That implementation can probably be neater but this is on the list of things to cleanup later
at this point.
In summary, the impact people will likely see after this change:
* Recipes may fail with missing dependencies, particularly native tools like gettext-native,
glib-2.0-native and libxml2.0-native. Some hosts have these installed and will mask these errors
* Any recipe/class using SSTATEPOSTINSTFUNCS will need that code rewriting into a postinst
* There was a separate patch series dealing with roots postinst native dependency issues. Any postinst
which expects native tools at rootfs time will need to mark that dependency with PACKAGE_WRITE_DEPS.
There could well be other issues. This has been tested repeatedly against our autobuilders and oe-selftest
and issues found have been fixed. We believe at least OE-Core is in good shape but that doesn't mean
we've found all the issues.
Also, the logging is a bit chatty at the moment. It does help if something goes wrong and goes to the
task logfiles, not the console so I've intentionally left this like that for now. We can turn it down
easily enough in due course.

This variable is used by libtool to know what paths are on the default loader
search path. As we have modified loader paths, cross.bbclass can tell libtool
that both the sysroot libdir and the host library paths are searched, so no
RPATHs for those will be generated.

cross-compilers are native recipes that need to be compiled by the host's

It turns out writing the same list of packaging tasks multiple
times in multiple places is error prone. Move this to a new class
'nopackages", migrate existing users and add glibc-initial and
libgcc-initial since we don't want packages for those recipes.
This means the sstate for those recipes won't be installed, saving
small amounts of build time and bandwidth.
A reference to the old package_write task is also dropped.

The gettext handling of USE_NLS has become a bit tricky to understand, or
alter from the SDK context. This patch introduces a SDKUSE_NLS which can
be set to configure a given SDK/ADT to use NLS or not. This is independent
of the target system NLS usage.
The code in gettext.bbclass is therefore simplified and the classes
themselves now set USE_NLS to appropriate values. No NLS is used
for native, cross and crosssdk since it is never used there and
would just increase build time.

Add the ability to dynamically change the library directory from "lib" to

A variety of approaches have been attempted with this, the immediate

${baselib} variable is retained in the expressions resolving that complication.
