Yes - it is the toolchain described by Andreas Junghans:
www.lucid-cake.net.
Currently, I am trying to make a more generic toolchain-generator based
on crosstolls for MacOS X - but there are still unsolved issues with
libiberty cross-compilation.

That is the most complicated part of cross-compiling - and although
there are libffcall and libavcall, it is not sure that everthing works.
I had taken the painful path of removing everything from mGstep first
and basing it only on the gcc-builtin functions, but AFAIK, currently
GNUstep is most advanced in properly using one of these libraries.
