The new naming has been introduced in gcc-8, so there should be no issues even for backporting the package to old systems. What is the oldest supported compiler for ffmpeg? BTW this is just an idea of a patch, other people might want to patch all the arms for the new gcc-11, but I don't know how to change them because I don't have the hardware so I just patched the Debian/Ubuntu used one. Feel free to change it if you like, or just take it as reference for people experiencing build failures with gcc-11. Hopefully somebody with the required hw will patch it in a better way once the gcc-11 becomes default on more systems. I sent a new patch version with different commit message.
