The default for ARM is "any", which is specifically for linux-user
and means "enable all possible user-visible instruction set options".
That means it should be able to run any guest binary OK.
Some other target CPU types do this, but not all; I think that
ideally we should convert them to do similarly.

I agree that the cases where we've picked some specific CPU
to be the linux-user default are a bit dubious.
