In theory yes, but at the moment my C compiler is very tied to the x86 platform (there is no separated code generation module, emit calls are directly in the code). Since the compiler is very simple, though, it should not be difficult factor out the handful of machine code gadgets that need to be implemented and add support for other back ends, I think. Or you might also other consider other ways, like using the toolchain in OP's repository.
If you want to have some brainstorming on #bootstrappable at freenode, there are often interesting discussions on these things.
