There were a few straggling expansion parameter removals left for
getVar/getVarFlag where the odd whitespace meant they were missed
on previous passes. There were also some plain broken ussages such
as:
d.getVar('ALTERNATIVE_TARGET', old_name, True)
path = d.getVar('PATH', d, True)
d.getVar('IMAGE_ROOTFS', 'True')
which I've corrected (they happend to work by luck).

ARM stack frames for abort and raise were limited to the the actual
abort and raise call, such as:
Obtained 4 stack frames.
./test-app(print_trace+0x1c) [0x10a08]
./test-app() [0x10b3c]
/lib/libc.so.6(__default_sa_restorer+0) [0x4adae1e0]
/lib/libc.so.6(gsignal+0xa0) [0x4adacf74]
This is not terribly useful when trying to figure out what function
may have called called the abort, especially when using pthreads.
After the change the trace would now look like:
Obtained 8 stack frames.

When changing SDKMACHINE, we may encounter an error forcing us to wipe the TMP folder.
Since only SDK_ARCH is captured in the PN of the crosssdk recipes, changes to SDK_OS
result in conflicts. Eventually we hit the error:
ERROR: ...: The recipe <...> is trying to install files into a shared area when those files already exist.
The build has stopped as continuing in this scenario WILL break things
This patchset addresses the problem by SDK_SYS as the recipe name suffix instead
of SDK_ARCH.

The ELF specification indicates symbol resolution should be breadth first, not
depth first.
The dl-deps.c: dl_build_locale_scope function is processing in a depth first
mode. This is causes certain symbols to be incorrectly reported when

The nativesdk libc when used by buildtools has a hard requirement on supporting
a UTF-8 locale because Python 3 needs a UTF-8 locale. However we currently only
ship the C locale, which means that Python attempts to lookup the user's locale
(for example, en_NZ.UTF-8) in the locale archive under it's prefix it fails and
falls back to C. This the results in Python using ASCII instead of UTF-8 for
file encoding, and bitbake breaks.
Th obvious solution would be to ship all locales, but this would add
approximately 250MB to the size of the buildtools tarball (which is currently
around 30MB). Generating a binary locale archive reduces this down to 100MB,
but this is still a drastic increase in footprint. If we ship a subset of
locales in the tarball then there will be users whose locale isn't in the
tarball, and they'll have to change their locale to an "approved" one, which
isn't the best of messages to send to new users.
The alternative is to tell the nativesdk libc that the locale archive isn't
under it own prefix but is in fact at /usr/lib/locale/locale-archive, so the
buildtools libc uses the host locale archive. The locale archive format appears
to be at least fairly stable: our glibc 2.24 can read the locale archive
generated by glibc 2.17 (Centos 7).

glibc master added the EM_METAG tag but didn't add the relocation defines.
However the kernel tooling only checks for EM_METAG when defining its own values
so scripts/recordmcount ends up using R_META_* symbols without their definition.
Whilst the kernel can and should be fixed, this breaks all users of recordmcount
so patch elf.h to add the values.

Currently locales are not found in a relocated buildtools-tarball
such as that used in eSDK. This breaks bitbake when used under python3.
This patch adds enough relocation magic to nativesdk-glibc so that
the binary locales can be found even in a relocated buildtools-tarball
and bitbake works successfully under python3. The eSDK also works
correctly after this change too.

python3 has much stricter locale requirements than previous versions.
If a locale isn't present, python3 reverts to ascii mode under which
bit
bake can't operate.
We therefore need working binary locales in things like uninative-tarball and buildtools-tarball. This patch enables binary locales for nativesdk-glibc.

Yocto's ldconfig-native was exported from an old version of glibc and
generates an ld.so.cache that is partially ignored by current versions
of glibc when loading libraries. This occurs for 64-bit binaries, where
glibc expects FLAG_ELF_LIBC6, but ldconfig-native only generates the
standard ELF flag. Fix this with an additional patch on top of the patch
for now.

We're seeing various failures where nativesdk glibc can't find the gconv
modules. We've tried various workaround but this needs fixing 'properly'.
One significant problem is knowing when a binary would use this glibc
and hence when to set the path and when not to.
Add the default path to its own special section which the sdk
relocation script already knows how to handle and remap.
This significantly improves the usability of uninative.

- Avoid code duplication to handle -O, -O1 and -Os cases
- Consider the effective optimisation level only (avoids spurious
warnings if multiple optimisation flags are present).
- Prefix warnings with PN instead of hardcoding "glibc" (avoids
confusing warnings since the test is also applied to glibc-initial,
nativesdk-glibc, nativesdk-glibc-initial, etc, and each could
potentually have different optimisation flags).

'nopackages", migrate existing users and add glibc-initial and

A bug in glibc 2.22's ld.so interface for the prelink support causes
the displayed values to be incorrect. The included path fixes this
issue.
Clear ELF_RTYPE_CLASS_EXTERN_PROTECTED_DATA for prelink
prelink runs ld.so with the environment variable LD_TRACE_PRELINKING
set to dump the relocation type class from _dl_debug_bindings. prelink
has the following relocation type classes:
where ELF_RTYPE_CLASS_EXTERN_PROTECTED_DATA has a conflict with
RTYPE_CLASS_TLS.
Since prelink doesn't use ELF_RTYPE_CLASS_EXTERN_PROTECTED_DATA, we
should clear the ELF_RTYPE_CLASS_EXTERN_PROTECTED_DATA bit when the
DL_DEBUG_PRELINK bit is set.
