oh wow, yes, I am! It's on a slightly older installation (gcc version
8.5.0 20210514 (Red Hat 8.5.0-18)), but there are a lot of basic build
failures, I'll get them together and send out a note.

Meanwhile, if you would like to try a quick fix, I have one that fixes
the problem on my system. I'm inclined to dress it up with a comment
that explains it (with a "TODO: stop using recursive Make here"), and
send it out as an actual fix:

diff --git a/tools/testing/selftests/arm64/Makefile b/tools/testing/selftests/arm64/Makefile
