I wasn't aware there's a way to list tests! That should work well
enough we can run them one by one with make, that's fine.

./run_kselftest.sh only seems to work for installed tests, tho,
in tree it says:
./run_kselftest.sh: Could not find list of tests to run (~linux/tools/testing/selftests/kselftest-list.txt)
So perhaps the wishlist item would be "make list_tests"?
