Why not do it the other way around?  Leave the default alone, but
add a separate target for -requires-unoptimized.

1-5 hours.  If you haven't run "make bootstrap" yet, then add
another 1-5 hours to that total, to accommodate fixing bugs in GUB
to allow it to complete that step on your computer.

These estimates do not include the 5-20 hours that your computer
will spend compiling software in the background.  Do not even
think about attempting this inside virtualbox.

I don't think we want to be shipping unoptimized binaries.
