I meant something like -m68020-60:
-m68020-60
Generate output for a 68060, without using any of the new instruc-
tions. This results in code which can run relatively efficiently
on either a 68020/68881 or a 68030 or a 68040. The generated code
does use the 68881 instructions that are emulated on the 68060

Right. We've got two different problems going on here.
