This will work technically but I still feel this is wrong semantically.
The pre-Paolo and current way is picking specific files from the hw/kvm/
directory. Your change above implies that in hw/kvm/ only x86 files can
live, which I dislike. As suggested before, I would prefer if x86-only
files were moved to an x86-specific location - the place for that
existing since Paolo's refactoring would be hw/i386/. CC'ing Jan. That
would match Paolo's reply in the unicore32 thread on future file
placement. Alternatives would be hw/i386/kvm/ or hw/kvm/i386/; we're
talking about a handful of files only though, so I don't think they
require a new subdirectory.
