Yes that's the intention. I'm also fine reverting this change; after D144509 <https://reviews.llvm.org/D144509> lands which presumably will be soon, we should be able to just use `check_linker_flag` directly.

I suspect we'll want to use more common modules in the LLVM build in the future though so we'll need a better solution to avoid future such failures.
