[HEADSUP] bsd.perl.mk import coming soon

[Mark Linimon]

The refactoring that gabor has done to recreate bsd.perl.mk will be
imported soon, along with the many ports that it simplifies.  Due to
the size of the patch, I expect there to be collisions that I will have
to adjust as I go, so expect the tree to be broken briefly while I work
through the checkin.

The main feature of the change will be to allow USE_PERL5= 5.8.0+ (and
similarly for USE_PERL5_RUN, USE_PERL5_BUILD, PERL_CONFIGURE and
PERL_MODBUILD).  As a side-effect, the remaining few stragglers that
attempt to keep perl5.003 going will be dropped.  (Other committers
have also been removing that code).
