If you insist to use -m68040, you still would need the additional
-Wa,-m68030 to make gas understand the inline assembler in (e.g.)
machdep.c, amiga_start.c for cache manipulation, _which is incompatible
between cpus!_ and thus handled by 68020/30 assembler opcodes and .word
instructions for th 68040 and 68060. Read the code if you want to
understand the details.
