Mono for powerpc64 could not, at least at the moment, cross compile
for a powerpc architecture.

Fixes:

The failure is in building host-mono, so I'm not sure why you think the
target architecture would matter?

I have sent a patch to simply unconditionally only make mono available
if you are building on a x86/x86-64 host, similar to how we recently did
for erlang.
