  28 #       use the minimum processor type of the range we support. The logic
  29 #       for 680x0 will only allow use of the -m68060 or -m68040 if no other
  30 #       680x0 type is specified - and no option is specified for 68030 or
  31 #       68020. The other m68k/ColdFire types always specify some type of
  32 #       compiler cpu type flag.
