prevent overwriting custom make options in ports

[Anton Shterenlikht]

I use ports/lang/gcc42.
I set WITHOUT_JAVA=yes in the Makefile.
However, with each tree update this option is
overwritten, so I have to edit the Makefile
each time I update the port.

What is the best way to preserve my custom setting,
add an environment variable?

many thanks
anton
