If "the expat license" is in fact MIT (hard to tell as there is no license
text in the ffmpeg sources), I do not see why we would need a special license
for it. All other recipes use "MIT" without creating a specific license file.
This includes the expat recipe itself, which use "MIT" as license.

ffmpeg does not produce any ptest package AFAICT.
