No dice.  All it does is call a different compiler instead of
/lib/ccom:  /lib/ccom20 if you say the CPU is a 68020, /lib/ccom20.81
if you want the 68881.  And you can't use the 68881 unless you also
specify you want the '020.

I don't know about anyone else, but I don't even have these other
compilers (not that I'm surprised).
