In fact having thought about it a bit I'm going to go further
and say that the whole idea of a "default machine" is a rather
x86-centric idea -- most architectures don't really have a
single machine type that's used by just about everybody,
always has been, and isn't likely to become obsolete in the
future. So if we're reworking the command line API to
supersede "-M" then we shouldn't have a default at all.

(Consider also the possibility of eventually having a single
qemu binary that supports multiple architectures -- that
would make a 'default machine' definitely a bit odd.)
