    Even if the identification can't be done automatically, it still seems
    like it would be good to start identifying ports that don't support -O
    by hand, and having the ports force a correct -O setting. Most ports
    support -O2 (if not -O3), and it would be nice if people could just put
    that option in their make.conf and be done with it.
