For ARM you absolutely should not be relying on the default
machine type (not least because it's an incredibly ancient
dev board which nobody uses any more). An ARM kernel is
generally fairly specific to the hardware platform being
emulated, so you should know which machine you're intending
to run on and specify it explicitly.

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.

That's not exactly true. For PPC, everyone so far expects a Mac to pop up.

Except if you're running on an IBM Power box, then you definitely expect a pseries guest to pop up.

We really need to enable the default config file (yes, we have a default config file) can express the default machine.
