When fixing build issues, please either a reference to an autobuilder
failure being fixed (for example in this case
https://autobuild.buildroot.net/results/53d/53daf0b4bd8b476252ca219e53a966405ece7e51/build-end.log)
or if none is available, a defconfig that exhibits the issue.

Patches must have a commit log, a Signed-off-by line, and an Upstream:
tag showing that they have been submitted upstream.
The Git repository is at https://code.videolan.org/videolan/libmpeg2.
Best regards,
