Cool.

There are cases when things break in one or another way if you enable
optimizations for all the builds, in make.conf.  The warning near the
description of CFLAGS in `/usr/share/examples/etc/make.conf' is there
exactly to avoid this sort of thing:

# Note that optimization settings other than -O and -O2 are not recommended
# or supported for compiling the world or the kernel - please revert any
# nonstandard optimization settings to "-O" or -O2 before submitting bug
# reports without patches to the developers.

So, unless there is a measurable performance gain which doesn't also
result in strange build- or runtime errors, I guess you don't need to
worry about it too much :)
