Simple answer: no. The build system only needs the variable up and including the equal sign.

It acts as an override.
Use something like ports-mgmt/poudriere or ports-mgmt/synth to build your own packages with your own options/defaults. Much easier to use.
That's certainly not the case on FreeBSD, the CDDL is compatible enough with the BSD license.
