This only affects the clang + libstdc++ combo. MSVC and gcc are fine.

clang has a bug that causes std::variant compilation to fail with libstdc++ from gcc-7. Apparently the bug is not fixed yet, not even in the latest clang trunk. This sort-of makes clang with std::variant a bit unusable currently. We could maybe force eos::cpp17::variant to alias to MPark.Variant for that combo.
