Ralf, could you please add the patch? It will give libraries a proper
major version number (by having it reflect the library ABI rather than
$current).

It will not cause breakage since existing libraries will continue to
use the ltmain.sh script they ship, while version downgrades in future
libraries will be handled by FreeBSD port maintainers, as a version
bump would be.

The goal is to allow us to gradually fix the version numbers by
upgrading the libtool port and then forcing existing ports to use that
new libtool.
