If there are to be binaries compiled for ColdFire then I'd suggest to
add some CPU checking code into the crt.S to detect when it's not
running on a CF compatible processor and halt in such case. I think that
ColdFire is not compatible with m68k so it would be unfortunate if m68k
people would try running ColdFire code.

If there is going to be a specific version of libraries, manually
adjusted assembler code and GCC compiling new binaries for the specific
target then I don't get why bothering with overpriced ColdFire boards
when you can get magniture faster computers based on VIA or AMD
processors, get them cheaper and get them now.
