Instead of having a new CPU model called "best", we can simply make
"-cpu host" available on TCG. I have submitted a patch for this
yesterday:

I think we've ended up with '-cpu max', present since QEMU 2.9 for x86
and perhaps for some other architectures, but not Arm yet.

As far as I can see, we have "-cpu max" now for x86, arm, ppc and s390x
... is that enough, so that we can close this bug now?
