You should add a testcase as Rafael pointed out. Overall it looks fine.
We used `mllvm` in lld to pass this kind of options to the backend but this seems justifiable.
BTW, if you're using lld or the gold plugin you might consider implementing the linker counterpart as well (if you have your proprietary linker, just ignore this last bit).
