KBUILD_DEFCONFIG := multi_defconfig

Enable processor type. Ordering of these is important - we want to

use the minimum processor type of the range we support. The logic

for 680x0 will only allow use of the -m68060 or -m68040 if no other

680x0 type is specified - and no option is specified for 68030 or

68020. The other m68k/ColdFire types always specify some type of

compiler cpu type flag.

Select the assembler head startup code. Order is important. The default

head code is first, processor specific selections can override it after.
