Mentioned on IRC but think this is a bug in the patch I added to enable CET. Will fix.

This also fixes build failures in some cases on < i686 in the same environment aforementioned.

Doesn't seem to have affected many people at all (just tinderbox?) so not worth a revbump (at this point, anyway). Also includes fix for i486 CET (unrelated).
