Fixed removing of obsolete shared libraries:

- the directory was wrong if ${SHLIBDIR} != ${LIBDIR}.  It's still wrong
  if the installation of the obsolete library was done before /aout was
  appended to LIBDIR.
- the version would have become wrong when the default in ../Makefile.inc
  is changed from 2.0.
- the comment mostly described moving of libraries to /usr/lib/compat, but
  we don't do that.
