Hi,
OpenEmbedded-Core/meta-linaro:

OE-Core shouldn't care, but the GCC and GLIBC do have to match. The
GLIBC patch is in trunk, should be in the upcoming 2.16, and I'm
looking into a backport for 2.15.(2?).
The current master branch of OE-Core happens to have the libc patched
already [1]. I therefore backported r114985 of Linaro GCC 4.7 to 4.6
[2] and everything works as expected. We now have single a base that
allows us to build all three images on all supported QEMU targets with
the latest versions of Linaro GCC 4.6 and 4.7. The corresponding
versions are:
* openembedded-core 363424c
* bitbake: f8bf449
* meta-linaro: b4f5e10
There's only one patch I put on top of this [3] to disable the
-fno-tree-vectorice flag they turn on by default for armv7a.
* worked on getting OE-Core to build with Linaro GCC 4.7
* verified that the recipes for Linaro GCC 4.7 are working for ARM, MIPS,
PPC, X86, X86_64
* all images are working!
Awesome.
