The patches rtld-deadlock and rtld-builddeadlock have been MFC:ed and
are included in 4.8-RELEASE. Hence, we need not warn 4.8 users.
How-To-Repeat: make openoffice on FreeBSD-4.8-release. a warning is issued that you
need two patches to rtld, but both are already in the
bugs -> openoffice
Committed, thanks !
