I have indeed joined. I just didn't have anything to say. :)

It actually is _very_ possible to use the same toolchain for both
uClinux and for normal Linux systems. The default file format
for uClinux is a FLAT file (as opposed to the ELF format used for
standard Linux systems). When you build the toolchains that are
linked to above, the default file format is ELF. You have to add
an additional option to gcc (-Wl,-elf2flt) or the linker
(-elf2flt) in order to convert the output file into FLAT format.
So yes, you can have just one toolchain that does it all.

Many people doing coldfire use uClinux-dist either by grabbing the
stupendously huge tarballs from
http://www.uclinux.org/pub/uClinux/dist/
or by grabbing things from CVS:
http://cvs.uclinux.org/
There is plenty of useful uClinux information available on:
