[BUGID #374]
The poison directory patch that was included with gcc-4.5.0 was not previously
enabled due to the lack of the configure file changes.
The patch has been updated to include the configure fragment. It was also noted
that this patch preformed nearly the same functions as the
zecke-no-host-includes patch, but with slightly different directories.
The directories scanned were added from the zecke-no-host-includes patch to
the new gcc-poison-dir-extend.patch.
The other difference with the zecke patch is that poisoned headers is no longer
an immediate fatal error. There may be instances where someone wants to do
this.
Adding -Werror=poison-system-directories to the CFLAGS would restore the
behavior.
Also fix a small problem where --help=warnings on gcc wouldn't return the
poison-system-directories as a valid option, even though it was.

gcc uses hardcoded path "${with-build-sysroot}/usr/include" to check target
libc ssp support. Based on GLIBC version strings in features.h in that search
path, gcc knows whether target (e)glibc implements stack protector itself.
However this breaks meta-toolchain, which actually has target libc headers
installed under {with-build-sysroot}/opt/... This way features.h is not found
and thus gcc-crosssdk-intermediate thinks that target (e)glibc doesn't support ssp.
Later when building eglibc-nativesdk, undefined reference to "__stack_chk_guard"
occurs which was caused by:
o eglibc do_configure found that gcc-crosssdk-intermediate supports ssp,
and thus enable -fstack-protector for nscd
o eglibc itself supports stack smash proctection for some architectures such
as i386, x86-64, etc. It's expected to use its own method to provide stack
protection, instead of relying on gcc. So eglibc rtld.os doesn't export
__stack_chk_guard to other modules
o then when installing nscd objects, gcc-crosssdk-intermediate sees the
flag "-fstack-protector", while it thought this eglibc doesn't implement
ssp itself, so gcc turns to the alternative to find a valid
__stack_chk_guard exported. eglibc doesn'g export it, while
gcc-crosssdk-intermediate itself disables libssp.
Then the undefined reference happens. If enabling libssp for gcc-crosssdk-
intermediate, it may also work-around this issue. But the ideal fix is still
to replace hard coded path with the actual one where target libc gets installed.
glibc-nativesdk doesn't encounter this issue because it thinks gcc doesn't
support ssp, and thus doesn't enable "-fstack-protector" for nscd. Don't know
the reason yet
This fix [BUGID #366]

If not configured with --enable-target-optspace, gcc will report
errors if there is '-Os' optimization in parameters.
This fixes [BUGID #342]
Also add "--enable-target-optspace" option to arm gcc configuration.

Fix the out of memory when building webkit-gtk with gcc-4.5.0
The new feature added after 4.3.3
"http://www.pubbs.net/200909/gcc/94048-patch-add-support-for-rmipsjalr.html"
will cause cc1plus eat up all the system memory when build webkit-gtk.
The function mips_get_pic_call_symbol keeps on recursively calling itself.
Disable this feature to walk aside the bug.

Fix one parameter order issue for base_contains function,
which impacts glibc build under new gcc.
Add new judge code to determine whether <altivec.h> is needed.
This fixes the mpeg2dec build failure under new gcc.
Use O2 as the optimization flag to tinylogin as it will meet
segfault if compiled by gcc-4.5.0 when enable both frename-registers
and Os options. Use O2 instead.

accross different gcc versions causing build failures

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.
