This fixes bootstrap for the current problems building libffi.
I'll work on getting this into upstream as well. If the maintainers
want it done differently, at least we have bootstrap working again
until then.
Tested on powerpc64-linux {-m32,-m64}.

* src/powerpc/linux64.S: Enable AltiVec insns.
* src/powerpc/linux64_closure.S: Ditto.

Ah thanks :-) I thought I'd get it fixed upstream soon, but that might
not happen (or not in time, etc.) This is a good idea no matter what.
