This is definitely something that would be great to see from the Power
side of things, especially as we're getting to the point where we'd like
to start dropping the build overrides in arch.mk and building the rest
of xen/common/.

As we get to that point, I was wonder if upstream would be fine with
submission of patches that add stub files for ppc in the interim, to be
removed later when this proposal is finalized and a solution is decided
upon. It'd obviously be best to avoid too much duplication of effort,
but at the same time we'd like to avoid getting blocked on progressing.
