[[ Emrun ]] Add --emrun flag to emscripten builds

montegoulding · montegoulding · commit 21a2ce9b5730 · 2017-07-26T09:06:47.000+10:00
The `--emrun` flag is only erquired when linking. It injects
some code so that if requests come from localhost it will post
stdout and stderr back to the requesting server. This will be
used by our test suite and by our HTML5 deploy library.
