I do not think that it makes much of a difference in your case, but I
could be wrong, of course.
Perhaps simply wait until the inevitable package upgrade(s), then
recompile with those flags?

I recommend leaving out -O2; this is something that should be set on a
per-package basis.  Also, look into devel/cpuflags; I think this would
suit you better than manually specifying it.  If you desire further
optimization, you can always

.sinclude "/usr/pkg/share/mk/"

after installing cpuflags.  Personally, I spend enough time fixing
broken things that I don't wish to contend with ``bleeding-edge'' gcc
optimizations as yet another cause of untoward program behavior.
