	I'm pretty sure it defaults to 68020 or above. Ideally the
	default should run on 68020 or better, with instruction
	scheduling set to give reasonable performance across the
	board. -m68020 should specifically set the instruction
	scheduling to maximise performance on a 68020 even if it
	significantly impacts performance on a 68030 or better.

	Whether it does is another matter :) Though if it does at
	some later point cpuflags is ready for it :)
