Hello, In fact, I'm not a kind of ffmpeg developer at all. While trying to link libcdio library with ffmpeg, I just happened to find out the way...
So I'm not sure I can answer any question about this configure script change...
I have tried to use libcdio function with ffmpeg on macOS. Then I get an
information from libcdio team. That is ffmpeg configure script should read
libcdio's pkgconfig file, libcdio.pc.
So I tried and error, then found that the below change should be done to link
libcdio library with ffmpeg on macOS.
$ diff -u a/configure b/configure

Please review it and make it acceptable for everyone...
