GCC 4.4.x looks to be adding support for generating out-of-line register
saves/restores based on:
http://gcc.gnu.org/ml/gcc-patches/2008-04/msg01678.html
This breaks the kernel build as we'd have to link with libgcc to get the
implementation of the register save/restores.
To workaround this issue, we just stole the save/restore code from gcc
and simplified it down for our needs (integer only). We only do this if
PPC32 as gcc makes believe the linker on ppc64 will deal with this and
only if CONFIG_CC_OPTIMIZE_FOR_SIZE is set (thus -Os).

If someone using cutting edge toolchains for ppc64 could test and make
sure if we enable CONFIG_CC_OPTIMIZE_FOR_SIZE things work that would be
nice.
