One part that I haven't looked at closely yet is x86's Makefile prefixing everything with $(OUTPUT). That seems something that should be consistent across target Makefiles if it exists at all, but clearly isn't. Maybe it was when it was introduced in commit a8ba798bc8ec. So, we could opt out only TEST_FILES. But that still leaves a branch there indefinitely and makes the option harder to understand. Sounds like TEST_PROGS_RECURSE is simpler then, indeed. Separate from the above, runner.sh also needs a few changes. This part is mostly cosmetic, but there will be duplicate basenames, for common terms such as client.pkt - TEST_HDR_MSG="selftests: $DIR: $BASENAME_TEST" + TEST_HDR_MSG="selftests: $DIR: $TEST" run_in_netns and run_many need similar fixes to avoid name collisions. Btw, for KSELFTEST_PKT_INTERP it probably makes sense to only try this if the script is non-executable, similar to the existing opt-out that looks at the shebang.
