For this specific case, the plan is to get rid of these empty PE files
and make it possible for mmdevapi to load the appropriate Unix backend
directly. Presumably the same mechanism could then be used to handle the
ws2_32 case.

Of course that doesn't change the fact that hardlinking files behind our
back is not a good idea on NixOS's part.
