selftests: bpf: fix compilation with out-of-tree $(OUTPUT)
A bunch of related changes lumped together: * Create prog_tests and verifier output directories; these don't exist with out-of-tree $(OUTPUT) * Add missing -I (via separate TEST_{PROGS,VERIFIER}_CFLAGS) for the main tree ($(PWD) != $(OUTPUT) for out-of-tree) * Add libbpf.a dependency for test_progs_32 (parallel make fails otherwise) * Add missing "; \" after "cd" when generating test.h headers Tested by: $ alias m="make -s -j$(nproc)" $ m -C tools/testing/selftests/bpf/ clean $ m -C tools/lib/bpf/ clean $ rm -rf xxx; mkdir xxx; m -C tools/testing/selftests/bpf/ OUTPUT=$PWD/xxx $ m -C tools/testing/selftests/bpf/ Fixes: 3f30658830f3 ("selftests: bpf: break up test_progs - preparations") Fixes: 2dfb40121ee8 ("selftests: bpf: prepare for break up of verifier tests") Fixes: 3ef84346c561 ("selftests: bpf: makefile support sub-register code-gen test mode") Signed-off-by: Stanislav Fomichev <sdf@google.com> Acked-by: Yonghong Song <yhs@fb.com> Signed-off-by: Daniel Borkmann <daniel@iogearbox.net>
