We explicitly set the hash style to gnu in our LDFLAGS. Setting the default to
this in the toolchain, while convenient, actually hides bugs, as a failure to
obey LDFLAGS isn't noticed. By removing this, it's not dissimilar to how we
poison the sysroot -- rather than relying on the default, notice right away if
somoeone isn't obeying the needed flags.
This will result in a failure to obey LDFLAGS causing a GNU_HASH QA failure,
which is what's often seen with external toolchains. This brings us all on the
same page, and makes sure a failure to obey LDFLAGS is seen early.
This is limited to cross, to retain ease of use for SDKs.

If configure or any of the components it uses from the shared work directory
change, do_configure may fail.
An existing do_preconfigure was created to handle these conditions, but
a 'sed' operation was missed, and a call to gnu-configize was also missed.

Various pieces of the code assume that the --sysroot option gets passed
into the compiler tools. By having a "sane" default, we don't always
spot when this occurs and this can later show up as breakage in sstate,
or in usage of the external toolchain.
We've long since talked about poisoning the default such that it will
break unless the correct option is specified. This patch does just that.
If this patch causes something to fail to build, it most likely means
the various compiler flags and commands are not correctly being passed
through to the underlying piece of software and that there is a real
problem that needs fixing, its not the fault of this patch.

It was observed that code using STLport 4.6 fails to compile under the
SDK with the following error message:
.../includes/cstddef:38:46: fatal error: ../4.7.2/cstddef: No such file
or directory
STLport 4.6 (screwily) assumes that the C++ system headers live in a
gcc-versioned subdirectory, for gcc>=3.0; cf
http://sourceforge.net/p/stlport/code/ci/STLport-4.6-patch/tree/stlport/config/stl_gcc.h#l269.
This assumption is *almost always* valid, because that matches the
default setting of --with-gxx-include-dir. We can match that behavior by
appending "/${BINV}" to our own --with-gxx-include-dir settings.

Since we no longer build target libs within gcc-cross, we can drop the
TARGET_CC_ARCH flags and hence make it independent of tune.

Rather than building the whole of libgcc to obtain the unwind.h header
file, simply configure it and then install the file. This avoids copying
chunks of data around when we don't need to and building the same thing
twice.
After doing this we need to make sure the target build directory exists
in the libgcc case since it will no longer be created automatically.

gcc 4.8 fortran presents some challenges:
* libquadmath headers need to be in the libexec include dir. It turns out
to be easiest just to manually do this.
* libgfortran configure needs libquadmath to be compiled. This means
a separate recipe is needed (the alternative is gross hacks)
* the libtool uses to link libgfortran doesn't have our improved rpath
handling and puts bogus RPATHS into the libraries. We can avoid this
by tweaking libtool with sed.
This patch resolves those issues. Any user of fortran does need to DEPEND
on libgfortran in order to trigger it to build but this shouldn't be a major
issue.

The include was useful historically, its not anymore so lets remove it.
This should have no functional change except on any layers directly depending
on it or gcc-cross.inc but even then it would only impact sh4 and is easily
fixed if there was a problem.

gcc-cross cannot build without linux-libc-headers but doesn't explicitly depend on
it relying on the implied dependency through libc. With cases where pieces
can be installed through sstate, we now need this explicit dependency to
ensure builds with partial sstate work.

gcc-cross is installed into a package architecture specific directory
and is not meant to be machine specific. This patch replaces MACHINE_ARCH
with PACKAGE_ARCH to ensure this is really the case.
This was found by examining sstate checksums.

This script will be generated into the build directory of gcc-cross
It should be testing gcc and g++. libstdc++ tests are not run since
we build them as part of gcc-runtime but we can test them here by
building them with 'make all' and then running the tests
The script expects passwordless ssh access to target and is used
in form
./arm-oe-linux-gnueabi-testgcc kraj@192.168.7.2

Having one monolithic packages directory makes it hard to find things
and is generally overwhelming. This commit splits it into several
logical sections roughly based on function, recipes.txt gives more
information about the classifications used.
The opportunity is also used to switch from "packages" to "recipes"
as used in OpenEmbedded as the term "packages" can be confusing to
people and has many different meanings.
Not all recipes have been classified yet, this is just a first pass
at separating things out. Some packages are moved to meta-extras as
they're no longer actively used or maintained.
