If one really wanted a library with these functions, I think there are
better places to copy the source from than glibc.

Not sure what you mean here... Are you talking about using these files
to kill processes that users left running after logging out? Or what?

Sounds like a good idea, but just stubifying it all sounds better.

-lutil is part of POSIX; in musl it's an empty .a file. I'm not sure
it would be a good idea to replace libutil with something else,
because programs using stuff from POSIX that's allowed to need -lutil
might add -lutil to the link command line.
