This means, the released binaries will never be compiled with this
optimizations (since they are expected to run on all architectures).
And that means, people doing benchmarks of the "out of the box"
installations, will find FreeBSD slower for "secure web-hosting".
Unless, of course, we provide different binaries on CDs.
