IMHO changing QEMU naming just for sake of making PPC look slightly
more like non-PPC architecture is not enough justification for making
an incompatible change like this. As you show above, regardless of
whether libvirt currently uses this feature or not, it hurts libvirt
because when we do add support we need to be able to cope with new
and old QEMU.  I'd suggest that commit is simply dropped unless there
is a clear functional reason for why the naming must be changed, not
merely a style reason.

Regards,
Daniel
