It's too annoying. Any make clean or make prints it. Also looking at commit f96afa767baf ("selftests/bpf: enable (uncomment) all tests in test_libbpf.sh") that introduced this stuff... I think it's all obsolete now. test_libbpf* can be removed. test_progs nowadays do a lot more than this mini-test. Doing a test with clang native | llc -march=bpf is still useful, but at this shape of test_libbpf it's pointless to continue doing so. Such clang native test should be properly integrated into test_progs. For now I suggest to remove this extra test_xdp.o recompilation and remove test_libbpf*
