Build of bpf and tc-testing selftests fails when the relative path of the build directory is specified.
make -C tools/testing/selftests O=build0 make[1]: Entering directory '/linux_mainline/tools/testing/selftests/bpf' ../../../scripts/Makefile.include:4: *** O=build0 does not exist. Stop. make[1]: Entering directory '/linux_mainline/tools/testing/selftests/tc-testing' ../../../scripts/Makefile.include:4: *** O=build0 does not exist. Stop.
Makefiles of bpf and tc-testing include scripts/Makefile.include file. This file has sanity checking inside it which checks the output path. The output path is not relative to the bpf or tc-testing. The sanity check fails. Expand the output path to get rid of this error. The fix is the same as mentioned in commit 150a27328b68 ("bpf, preload: Fix build when $(O) points to a relative path").

Looks god to me. I can pull this in for Linux 5.18-rc1

Does the same happen when you use make kselftest-all?
I am unable to reproduce what you are seeing?

No, this problem doesn't appear when using make kselftest-all.
As separate output directory build was broken in kernel's top most Makefile i.e., make kselftest-all O=dir. (I've sent separate patch to fix this: https://lore.kernel.org/lkml/20220223191016.1658728-1-usama.anjum@collabora....) So people must have been using kselftest's internal Makefile directly to keep object files in separate directory i.e., make -C tools/testing/selftests O=dir and in this way the build of these tests (bpf, tc-testing) fail. This patch is fixing those build errors.

make -C tools/testing/selftests O=dir should reproduce this problem.

Applied to linux-kselftest next for Linux 5.18-rc1.
