I put #warn instead of #error because they could well be using only the
other _BSD_SOURCE functions.

Feel free to start committing.
I may not be able to get all of the headers very soon, with my classes.
But this patch alone should solve at least one of Rob Landley's issues
with toybox (namely, chroot()).
