PowerPC: Move -fPIC flag to common place

The -fPIC flag belongs with -mrelocatable, move it there.
Also change -fPIC to -fpic as this produces smaller
binaries.
However, currently -mrelocatable promotes -fpic to -fPIC, a
fix for this is in upcoming gcc 4.6 or you can apply this small
patch to gcc:
