- -O3 and -O2 do nothing with -Wl,-O; it's a binary switch.

I'm currently looking into other things like --relax (which... does
what?  The man page is very vague) and anything else I can come across
that's harmless.  It's hard to know exactly what the environment on the
build server looks like though, since ubuntu doesn't seem to have this
documented anywhere I can easily locate... (one of the devs told me he
"thinks" -Wl,-O1 is in the ENV on the build server)

    new problems waiting out there.
