I had to give up. Without the CONFIG_PPC_FPU it compiles fine for an
FPU less 44x. But with the CONFIG_PPC_FPU, I get the following errors:

arch/powerpc/lib/built-in.o: In function `__copy_tofrom_user':

Oops, sorry, it will say arch/powerpc/lib/copy32.S... I corrected that.
But I cannot find how copy_32.S is including those functions.
