Possibility for FreeBSD 4.11 Extended Support

[Mark Linimon]

Community support will continue on the freebsd-eol mailing list, fwiw.
However, note that we have dropped the requirement for ports maintainers
to make their ports work on 4.X, although many continue to do so.

It is simply too much for the ports team to support 3 major branches and
one development tree (as per previous discussions).
