Different arches handle their command lines differently, but
with some elbow grease (and some buy-in from the different
arch maintainers), we could try unifying the approach here.

One difficulty is that the other arches' command lines
are not currently "broken", so there's no real incentive
to change them.

The only thing novel thing I'm adding here is the addition of
the leading '!' to allow for an override. This is needed
in some x86 cases I'm familiar with, but I've haven't seen
any cases where it would be useful for other arches.
(not to say they don't exist - I just haven't seen them.)
