Add an anti-foot-shooting measure to detect missing default Perl definition.

Browse source 
This can happen if bsd.perl.mk was not included before or during the
inclusion of bsd.port.pre.mk.  As of bsd.port.mk 1.586 this can't yet
happen, as bsd.perl.mk is included unconditionally, so this checkin should
be a no-op.

While here, reserve WANT_PERL for ports that conditionally depend on Perl.
WANT_PERL will need to be defined before bsd.port.pre.mk is included.
