powerpc/corenet64: compile with CONFIG_E{5,6}500_CPU well
If CONFIG_ALTIVEC is enabled for CoreNet64, and if we also
select CONFIG_E{5,6}500_CPU this may introduce -mcpu=e500mc64
into $CFLAGS. But Altivec option not allowed with e500mc64,
then some compiling errors occur like this:
CC arch/powerpc/lib/xor_vmx.o
arch/powerpc/lib/xor_vmx.c:1:0: error: AltiVec not supported in this target
make[1]: *** [arch/powerpc/lib/xor_vmx.o] Error 1
make: *** [arch/powerpc/lib] Error 2
So we should restrict e500mc64 in altivec scenario.
