We need --with-cpu based to glibc to get proper support on 603e& e500mc
to pickup proper math libs to deal with sqrt. These core do not
implement the fsqrt[s] instructions that the normal PPC math libs
utilize.
This causes use to not set AVAILTUNES specifically to the sub-arch only
as we arent generically compatiable.

v3:
- utilize TUNE_FEATURES for how we set GLIBC_EXTRA_OECONF

Kumar,
This patch is not applying directly it seems that you might have some
difference in the TUNE_FEATURES and PACKAGE_EXTRA_ARCHS_ that is
throwing things off, have you rebased against master?
Sau!
