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.
