Comment(by raimue@…):

 I am thinking about a separate group for `cc`. This would allow to choose
 between:

  * clang => /usr/bin/clang
  * llvm-gcc42 => /usr/bin/llvm-gcc-4.2
  * mp-clang => ${prefix}/bin/clang
  * mp-llvm-gcc42 => ${prefix}/bin/llvm-gcc-4.2
  * mp-gcc => ${prefix}/bin/gcc

 Adding a single symlink for gcc should be flexible enough as the version
 can be selected with the `gcc` group.
