It's trivial to spot: the x264 compiled with disable-gpl is different
with a quick "strings".  Something like this should work on an
executable, library, whatever:

strings x264.exe | grep -C2 "core %d%s" | head --lines=1

This will say "left" if GPL, "right" if not.  I've tested it on x264 and ffmpeg.

If you don't know if a company has a license, ask me.
