I don't believe so. LANGUAGES= only gets used as an immediate
dependency of something or other. That is why we have to have "c++:
cc1plus$(exeext)" in cp/Make-lang.in, but I don't think it affects the
need for c++.whatever rules at all. You'll notice that setting
LANGUAGES=c in a build with more languages enabled does not inhibit
the build of the g++ driver or the demangler...
