I didn't intend to disable them permanently.  Just identify them to implement
alternatives.

If the sysv abi cannot be used on 68000, 680x0 w/o HW FP, or at least some
Coldfire, then what is the alternative ABI?  GCC has rules on the ABI on those
targets.  Is it radically different or just slightly modified to accommodate
the differences?
