Target-independent attributes get enums, and target-specific attributes are
just strings: https://llvm.org/docs/LangRef.html#attribute-groups
We could potentially make this attribute target-independent if there is wider
interest in removing the reliance on bare `(...)` signatures to signify
prototypeless C functions. I would like to see more details of how we plan to
handle this in the backend before I have any idea about what anyone else might
thing.
