Being Jenkins being bogged down/broken recently and "make tinderbox", etc being broken, it's harder to track when things break unless you do careful inspection (speaking of which, this reminds me that I need to setup Jenkins at work to emulate jenkins.freebsd.org). I definitely appreciate knobs like this because it gives folks the ability to toggle things on/off if issues are found, either specific to their use case or not.

This change (for instance), might cause grief with an older/different version of gcc.
