tune-ppc: Update to pass glibc configure option to get cpu specific support

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.
