I think the reason of the failure is the missing of srctree. I skipped a patch [1] because I think it is independent with this patchset, but I was wrong. Could you please add the srctree setting code block from [1] to your tools/lib/bpf/Makefile and try again? You don't need other part of it, or you have to apply the whole patchset because it moves a file.
