With 2.0.4, emcc is complaining that EMMAKEN_COMPILER is deprecated. We had been using that to point to a little script snippet that forces Emscripten to invoke a (defined) clang together with gomacc to speed up compilation via goma. Given that EMMAKEN_COMPILER is deprecated now, it's unclear how we can achieve this? Maybe we could have goma officially supported in Emscripten instead?
