ffmpeg: Resolve hard/float builds with work-around dependencies

Hard float includes: libx264, mp3lame
Soft float includes: shine (mp3 encoder)

fdk-aac will not be available in libffmpeg-full due to incompatible license with libx264.
Custom builds can override licensing restrictions but results may not be re-distributable.
