I think we have to freeze the kernel headers along a distribution
release branch, and update them only insofar we backport things to
this distribution release branch.

My proposal aims to avoid a build order depedency between the
backports landing in the distribution kernel, and a glibc rebuild.
For point releases, glibc and kernel may be developed on different
schedules, and if the glibc build uses my proposed patch, it can use
the upstream system call list as a superset of what's going to be
backportable for the next point release.
