commit 8ce72dc32578 ("selftests: fix headers_install circular dependency") broke bpf build/test workflow. When KBUILD_OUTPUT is set, bpf objects end up in KBUILD_OUTPUT build directory instead of in ../selftests/bpf.
The following bpf workflow breaks when it can't find the test_verifier:
cd tools/testing/selftests/bpf; make; ./test_verifier;
Fix it to set OUTPUT only when it is undefined in lib.mk. It didn't need to be set in the first place.

'git am' couldn't apply this patch because "sha1 information is lacking", but the patch itself looks good. Acked-by: Alexei Starovoitov ast@kernel.org Thanks for the quick fix.
