COPT (and PROFILE) are handy for injecting additional flags manually;
they're even documented for that (cf installation.sgml, around line
1550).
I agree that CXXOPT would be a better idea than COPT for this.
Not sure about PROFILE. But we could inject the latter into both
flag sets and then document that if that's not what you want, use COPT.
