Same problem here. Fresh install of unity 5.4.0b10 under linux ubuntu 14.04.
After running the failing command from CLI, I do notice that it's relying on WINE to run the command for Failed running /opt/Unity/Editor/Data/il2cpp/build/il2cpp.exe which is then looking for python.exe and it isn't installed.
Could be the same issue with wine installed libs, or the fact that its looking for unity editor installed under wine, which is not the case with the native linux package. In the ext3 folders which wine would class as z: the folders exist up until Emscripten_Win which is non-existant, hence the file not found issue.
