Comment (by Peter.Danecek@…):

 IMO, I do not think, `gcc` and `g++` should be moved from gcc_select. The
 *_select ports are about where some common names, e.g. `ipython` or ``gcc`
 point (link) to, not necessary about to which ports, e.g. `gcc48` they
 have to point.

 So having a `gcc_select` port and `port select gcc ...` around which would
 not influence the `gcc` is contradictory. Instead, one could consider --
 if this is really what we want -- that `port select gcc ...` can be set to
 some `clang` versions as well. To my understanding there is no `cpp`
 binary is provided by clang.
