Other libc use a separate ld and libc, so they don't have this problem.
 musl uses one file, libc.so, as both tasks and it determines which way
it's being used.

ldconfig is making a mostly sane assumption that symlinks within lib
dirs which don't go anywhere should be removed as they're likely left
over from old libs which are not installed anymore.  Usually this is not
a bad thing to do.

The reason is that you may have a different syslibdir and libdir.  What
musl is doing is the right way for them, just annoying for us.

Yes, my script has the same problem.
