Instead of referring to the Linux header including the barrier
macros, copy over the rather simple implementation for the PowerPC
barrier instructions kvmtool uses. This fixes build for powerpc.

Hi,
I just took what kvmtool seems to have used before, I actually have
no idea if "sync" is the right instruction or "lwsync" would do.
Would be nice if some people with PowerPC knowledge could comment.
Cheers,
Andre.
