Remove obsolete options from make.conf manpage.

[Craig Dooley <xlnxminusx@xxxxxxxxx>]

This patch removes two options relating to perl (NOPERL and
PERL_THREADED) that don't apply anymore from the make.conf manpage. 
They have already been removed from etc/default/make.conf.  SUIDPERL
is left because the port still uses that variable.  Should that also
be removed as it is now a port option and not a base option?
