For C++ it is critical that we not build them if C++ isn't in
LANGUAGES. Why, because some of the code is written in C++.
Worse yet, if we didn't build C++ ourselves, then autoconf might
find a random copy of g++ lying around on the system. Instead of
failing loudly it might silently use g++-2.7 or something bad like
that :-)
This kind of problem is much less severe for runtimes that are
written in C like libf2c and libchill since C code is rarely
incompatible between releases.
