-e: see title. even an empty build fails on Windows and OSX.

-tested on Version 5.4.0b3 (6110a3bcdf6e), Tue, 26 Jan 2016 23:11:05 GMT, Branch: trunk. Worked on the previous beta build.

-repro:
--create new project
--start a webgl build for the empty project
--NOTICE it fails with IL2CPP errors

    On Arch Linux, python command is obviously on the path and refers to Python 3.5.1. There's also python2 command, referring to Python 2.7.11. Both are available in the PATH

    I'm not sure whether this is related, but on Arch Linux, Unity Editor 5.40b15, I'm getting this when publishing any project, even empty, to WebGL:
