You can also use LLVMC driver to easily define your own build flow.
see llvm/tools/llvmc/example/ directory and llvmc tutorial in llvm
documentation.
(and don't mix up llvmc and llvm-mc that's different tools)

But you need your own assembler/linker and the easiest way to have this
is to port binutils. You don't have to port GCC, only binutils is required.
