No arch/cpu-related optimizations are being set by default in most of the
packages. Perhaps there are a few exceptions, where the upstream settings
use optimization, or where the Debian maintainer has changed it, I don't
know.
I think we already had this discussion (which usually evolved in a flamewar
:), several times, and nothing was done to change the current status. Please
let's not rehash the whole issue once again.
