I'm thinking about creating the machine flag "COLDFIRE" in KERNELDEFS,
add it in the sources wherever the M68040 macro is used and then
remove the -DM68040 flag when compiling the MINTV4E.PRG.

Also I have seen that when compiling MINT020.PRG, the -D68000 flag is
used, this seems wrong to me. I think about creating the M68020
machine flag too that is missing now.
