Re: xen bits broke x32 build

[Michael Tokarev]

To clarify: I don't think this needs fixing for 8.0.

Yes, it's a regression on x32.  Xen has never worked on x32,
this just looks like forgotten case when it needs to be disabled
in qemu for x86. It's trivial to work around by adding a --disable
argument to configure.  And generally I don't know anyone actually
running qemu on x32. It's some exotic thing which apparently is
going away by its own.

Thanks,
