configuring ports via Makefile.local

[Radim Kolar]

There is a nice way to configure ports not supporting OPTIONS=
via Makefile.local. To make this method really work 
.include <bsd.port.pre.mk>
line must be placed in Makefile BEFORE making any checks for WITH/WITHOUT.

There is a problem with this:
1) portlint do not checks for it
2) most ports have included pre.mk too late in Makefile - options works
from cmdline only
3) i can not find note about this in porter handbook.
