This is what happens when you have not ported anything that required
anything beyond the basics since the "new" OPTIONS system came into place.

Clearly, you are right in the case of forcing opt2,  but, if all opt2 does
is set an option for configure or something similarly trivial, that does
not look to me like it would incur these problems. (I have no idea if it
does.)
