I might be missing an obvious, but I just don't see a reason
why we should use relative linking here: we should just link
to where we really install.  With the attached patch, I get:

$ make -n install -DNOMAN DESTDIR=/foo
install -C -o root -g wheel -m 444   libalias.a /foo/usr/lib
install -s -o root -g wheel -m 444     libalias.so.4 /foo/lib
ln -fs libalias.so.4 /foo/lib/libalias.so
ln -fs /foo/lib/libalias.so.4  /foo/usr/lib/libalias.so
