libebur128 was added to buildroot in July 2016 with commita32d29cd84to provide an external dependency for ffmpeg. ffmpeg removed this external dependency and switched to an internal version in November 2016 with upstream commit http://git.videolan.org/?p=ffmpeg.git;a=commitdiff;h=005d058f4230f3207ebcf1131df7426d4f57392f which was first included in ffmpeg version 3.3. Buildroot bumped ffmpeg to version 3.3 in April 2017 with commit21d93a1351and forgot to remove the dependency to libebur128. This went unnoticed until libebur128 fails to build with cmake 4.x. Upstream saw its last commit four years ago. Instead of fixing an unused package we removed it from buildroot.
