Well, they actually can, but they either need to point to sibling
directories (say /usr/bin -> /opt/foo/bar/bin, /usr/lib -> /opt/foo/bar/lib,
/usr/lib64 -> /opt/foo/bar/lib64) or if for whatever reason they are not,
then you need symlinks in both locations (say /usr/bin -> /opt/foo/bar/bin,
/usr/lib -> /opt/bar/baz/lib, then you'd need also /opt/foo/bar/lib ->
../../bar/baz/lib and /opt/bar/baz/bin -> ../../foo/bar/bin).

This is not just for the sake of $ORIGIN/.., e.g. gcc does a similar search
for libraries and other relocatable packages do so as well.
