  20#       Enable processor type. Ordering of these is important - we want to
  21#       use the minimum processor type of the range we support. The logic
  22#       for 680x0 will only allow use of the -m68060 or -m68040 if no other
  23#       680x0 type is specified - and no option is specified for 68030 or
  24#       68020. The other m68k/ColdFire types always specify some type of
  25#       compiler cpu type flag.
