This is exactly what --enable-languages is for, according.
<http://gcc.gnu.org/install/>.

In fact, according to that documentation, LANGUAGES is completely
unnecessary for regular users. (I think I understand what you are doing,
but I am not sure whether we want to expose such detail to the regular
users and whether this is "officially" supported at all.)

If this is not correct and LANGUAGES should be officially supported,
could someone please submit a documentation update for
<http://gcc.gnu.org/install/>?

Would you mind submitting a patch for install/test.html?

Thanks!
