I contend that any properly conditional means of adding those flags will
look completely different from 287a00b9a, so the change as it stands has
no value (not to mention negative value on some platforms).  I've already
locally reverted it just to get something that isn't broken.

Don't the buildbots have a way to specify environment variables?  Travis
certainly does.

It would also be useful to have the buildbots feed from a testing branch,
so that the master branch doesn't get used as a testing sandbox (e.g.,
016eda025/4ca79909a).
