Greg Ungerer 281eff5322 m68k: merge mmu and non-mmu arch Makefiles 
Most of the build logic is the same for the mmu and non-mmu m68k targets.
Merge the top level architecture Makefiles back into a single Makefile.

For the most part this is just adding the non-mmu processor types and
their specific cflags and other options into the mmu Makefile.

Note that all the BOARD setting logic that was in the non-mmu Makefile
is completely removed. It was no longer being used at all.

This has been build and run tested on ColdFire targets and ARAnyM.
It has been build tested on all the m68k defconfig targets using a
gcc-4.5.1 based toolchain.

# 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.
