license information Wiki

Hi 
I installed, the ffmpeg binaries using this npm package 
https://www.npmjs.com/package/ffmpeg-binaries

Do you build ffmpeg with the GPL flags off 
**Compile FFmpeg without "--enable-gpl" and without "--enable-nonfree"**
https://www.ffmpeg.org/legal.html

would be really awesome if we could update the wiki with this information.
