So that a single machine can build multiple architectures for the
uninative-tarball respect SDK_ARCH instead of BUILD_ARCH.
This means a x86-64 host can build a i686 uninative-tarball by setting
SDKMACHINE=i686.

This task is meaningless for uninative-tarball as the package task
has been deleted. Besides, sometimes it would cause problems. To
reproduce, use the following command.
bitbake uninative-tarball -c cleansstate && bitbake uninative-tarball &&
bitbake uninative-tarball -c clean && bitbake uninative-tarball
The error is something like below.
File: 'sstate.bbclass', lineno: 33, function: sstate_installpkg
0029: bb.build.exec_func(f, d)
0030:
0031: for state in ss['dirs']:
0032: prepdir(state[1])
*** 0033: os.rename(sstateinst + state[0], state[1])
0034: sstate_install(ss, d)
0035:
0036: for plain in ss['plaindirs']:
0037: workdir = d.getVar('WORKDIR', True)

DEPENDS doesn't actually add the dependency on patchelf-native to the
populate_sdk task. SDK_DEPENDS does this, but move the append to after
inheriting the base class so it does not get overwritten.
Without this, uninative-tarball fails to build in a clean workspace on a
system without patchelf.

uninative.bbclass uses -xjf for decompression so actually run the data
through bzip2.

These patches are the start of a new idea, a way of allowing a single set of
cross/native sstate to work over mutliple distros, even old ones.
The assumption is that our own C library is basically up to date. We build
and share a small tarball (~2MB) of a prebuilt copy of this along with a
patchelf binary (which sadly is C++ based so libstdc++ is in there). This
tarball can be generated from our usual SDK generation process through
the supplied recipe, uninative-tarball.
At the start of the build, if its not been extracted into the sysroot, this
tarball is extracted there and configured for the specified path.
When we install binaries from a "uninative" sstate feed, we change the
dynamic loader to point at this dynamic loader and C librbary. This works
exactly the same way as our relocatable SDK does. The only real difference
is a switch to use patchelf, so even if the interpreter section is too small,
it can still adjust the binary.
Right now this implements a working proof of concept. If you build the tarball
and place it at the head of the tree (in COREBASE), you can run a build from
sstate and successfully build packages and construct images.
There is some improvement needed, its hardcoded for x86_64 right now, its trivial
to add 32 bit support too. The tarball isn't fetched right now, there is just a
harcoded path assumption and there is no error handling. I haven't figured
out the best delivery mechanism for that yet. BuildStarted is probably not
the right event to hook on either.
I've merged this to illustrate how with a small change, we might make the
native/cross sstate much more reusable and hence improve the accessibility
of lower overhead builds. With this change, its possible the Yocto Project may
be able to support a configured sstate mirror out the box. This also has
positive implications for our developer workflow/SDK improvements.
