If you're using gcc and talking about compiling userland, the only real
differences that I'm aware of have nothing to do with the actual
instruction set used, but the optimizations that are done.  Code optimized
for the 040 should run on the 030.  Unless you specify otherwise, however,
the code that you produce will not be optimized for the 040.
