this is hairy. Seems easiest solution is to have a few shell scripts that
invoke the real compiler with the right '-m' switch. For some programms
it does also work to say CC="m68k-linux-gcc -m68040" but it can break
badly with libtool which apparently can't cope with that.

I think its not worth to do extra 68040 configuration, for libgcc,
libstdc and java it should be sufficiently similar to 68020/68881.
