The automatically chosen default for CFLAGS would be '-O2 -pipe'
(optionnaly additionally '-fno-strict-aliasing' depending on
FreeBSD version) these days and there should be no reason to
artifically limit optimizations to just '-O'.

This makes sense if you don't want to spend diskspace and CPU
cycles compiling profiled versions of libraries if you have no
use for them. Especially since FreeBSD/sparc64 doesn't support
userland profiling before 7.0.

With FreeBSD 7.0 and later this translates to WITHOUT_PROFILE=
(yup, no value) in /etc/src.conf.

I think in former versions this enabled compilation of some
crypto code which was export restricted. FreeBSD 6 and later
no longer check it.
