Yeah.  I certainly don't think we want a proliferation of such
mechanisms.  If minimal is already using MACHINE_CLASS then there would
be some sense in trying to make use of the same thing.

My preference would be to make the MACHINEs in question be, for example,
"motorola-ezx-a1200", "motorola-ezx-a780" and so on.  This would then
allow you to set COMPATIBLE_MACHINE = "motorola-ezx-.*" which I think
would solve the SOC_FAMILY problem, although it wouldn't replace
MACHINE_CLASS in OVERRIDES.

Failing that though, testing COMPATIBLE_MACHINE against MACHINE_CLASS
probably is more desirable than adding a completely new variable (i.e.
SOC_FAMILY) for that purpose.
