How can I specify an entry in mk.conf that will keep any options for getting
picked up (when they don't need to be).

My particular problem starts with mk.conf having:

PKG_OPTIONS.clamav =

But when I build clamav, it picks up:

PKG_SUGGESTED_OPTIONS=  curl

While I appreciate the suggestion, I don't want to build it with libcurl.
So I modify the Makefile, build, then manually make sure I get the new
Makefile when the mail/clamav package is updated.

What is the right way to skip the suggested options?

Thanks,

peter
