Ok, so it's not accidental/obsolete — that's all I needed to know :-).
Another thing I've noticed that clang needs `libomptarget.devicertl.a` even
when no GPU target is actually used. I've worked around that for now by
creating an empty `.a` file locally, but perhaps that should also be handled
better somehow (I can make a PR later if you tell me how you'd like it handled).
