Heh, the problem happens when it's user-specified but *not* missing,
just the wrong one.  If you're building an arm-linux glibc, and have
CC=arm-linux-gcc but CXX=g++ you get a mismatch because g++ *does*
exist.

If you *don't* set CXX, then yeah, configure can set it to "missing".
But recall my thoughts on configure guessing better ;-)
