If you use this feature, change /usr/pkg/etc/mk.conf entry to:
mk.conf will override the Makefile if "=" is used and that is not
desired. If the Makefile has DRAGONFLY_CCVER set, it's for a reason and
it shouldn't be overridden.
The "?=" means to set DRAGONFLY_CCVER only if it's not already defined.
