The plan is to remove /usr/bin/CC in head.  However, on older branches,
/usr/bin/CC will still exist.  In my opinion, cmake should prefer calling "c++"
over "CC", if the former is available, that is all.

Yes, but why would that be better than just fixing the C++ compiler
determination for all platforms?
