This is just used to fix a build error in powerpc.git when introduce commit cd66cc2e, "powerpc/85xx: Add AltiVec support for e6500", in *powerpc.git* as I mentioned in this patch head.

This change don't block your AltiVec support for kvm unless you think this change is wrong. And especially, we always can reproduce this error with/without enabling AltiVec, so I also don't think this should be suspended until support e6500 in kvm since kvm based on e5500 should work.
