How does this sound:

* we define, per operating system/version, a default c++ compiler,
  let's say gcc-4.9 (or whatever we think is the best version on that
  platform). this version is pulled in whenever c++ is defined in
  USE_LANGUAGES. It should support c++11.

* the user can override this default globally, before compiling packages
