However, you only need a Canadian Cross if you're trying to build a _cross-compiler_ that will run on a different system. If you're trying to build a compiler that will run on a different system but be a native compiler on that system, that's just standard cross-compilation of GCC (note!! Not making GCC be a cross-compiler!) I believe all you have to do is run the standard GCC build with the --host flag set to the target you want to build for, and appropriate configure flags (such as --with-sysroot) to find the alternative glibc and headers. Of course you need to deal with binutils as well.
