Take a look at *any* distribution's default optimization flags. For rpm-based distros, the default /usr/lib/rpm/rpmrc says 'optflags: amd64 -O2 -g'. In Debian, dpkg-buildflags returns 'CFLAGS=-g -O2' by default. Even in Gentoo, /usr/portage/profiles/arch/amd64/make.defaults says 'CFLAGS="-O2 -pipe"'.
