- 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.
