MR: https://gitlab.com/redhat/centos-stream/src/kernel/centos-stream-9/-/merge_requests/7244
JIRA: https://issues.redhat.com/browse/RHEL-107194
This Merge Request intends to fix an error with the buildcheck test QE runs. It builds the kernel using a separate output directory for the build artifacts. The core of the problem is that some backports in RHEL 9 are already using a new way to reference the source directory used upstream, but those backports failed to bring the necessary kbuild changes to use it. The core of the Merge Request here is commit "kbuild: use $(src) instead of $(srctree)/$(src) for source directory", which is the main change required. All other changes are dependencies/pre-requisites or fixes to this change. With changes below, using the build with a separate output directory is then fixed.
