I can't build the build libs with emsdk 3.1.50, i will open a separate issue for that, for now i will try with an older version but major of 3.1.32

The libs can be build with emsdk 3.1.40 the only issue that we have now: the log message from ARLOG's print in the console.error message (intead of console.warning, this change was done in version 3.1.39 ), i will change this behaviour.
