They don't get really penalized by non -m68060 system (about 1000 emulations/s
when a compiler is running), and can rebuild their system much faster then
the other way round, if they really care.

If we had a unified m68k binary distribution, we could afford 3 different
distributions... or maybe four:

- m680[23]0 without FPU
- m680[23]0 with FPU
- m68040
- m68060

But this will have to wait for 1.5, I'm afraid.
