libfdk_aac is incompatible with the gpl and --enable-nonfree is not specified

Hello. This is probably supposed to happen but I'm not sure. With ffmpegchoice and ffmpeglicense I selected these: ``` 2 = No (Light build) 5 = LGPLv2.1 [same disables as LGPLv3 + GPLv2.1] ``` Unexpectedly (to me), it built fdk-aac (the re-run is below) ``` Running git update for fdk-aac ... fdk-aac git ................................................ [Up-to-date] ``` However when ffmpeg `configure` runs we see this error. ``` libfdk_aac is incompatible with the gpl and --enable-nonfree is not specified. ``` Perhaps that is normal I'm not sure. I was hoping for a light build with minimal licensed stuff. Advice welcomed. Log: ``` Warning: We will not accept any issues lacking any form of logs or logs.zip!

If you think configure made a mistake, make sure you are using the latest version from Git. If the latest version fails, report the problem to the ffmpeg-user@ffmpeg.org mailing list or IRC #ffmpeg on irc.libera.chat. Include the log file "ffbuild/config.log" produced by configure as this will help solve the problem. configure failed. Check C:/MABS/build/ffmpeg-git/build-static-64bit/ab-suite.configure.log This is required for other packages, so this script will exit. Creating diagnostics file... Attach C:\MABS\build\logs.zip to the GitHub issue. Make sure the suite is up-to-date before reporting an issue. It might've been fixed already. Try running the build again at a later time. ```
