If you already have a cross-compiling environment set up, it shouldn't
be too hard; for LLVM and llvm-gcc, you should be able to pass in
--host=mytarget to configure, and if you're lucky, it'll just work
(but for llvm-gcc, make sure to read the README file first).

There's a script to compile a complete cross-compile environment plus
LLVM and llvm-gcc for ARM in
utils/crosstool/ARM/build-install-linux.sh in the LLVM tree; that
might be useful as a reference, depending on what you're doing.
