Every once in a while, a package requires a really up to date active compiler in order to build successfully. ecm.eclass had inherited such a mechanism, albeit GCC specific, from older kde* eclasses. I don't think that is a good place for it so I suggest to add a more universal function to toolchain-funcs.eclass.
Similar to tc-check-openmp.
