Commit5c26f9a783("libbpf: Don't use cxx to test_libpf target") converted existing c++ test to c. We still want to include and link against libbpf from c++ code, so reinstate this test back, this time in a form of a selftest with a clear comment about its purpose. v2: * -lelf -> $(LDLIBS) (Andrii Nakryiko) Fixes:5c26f9a783("libbpf: Don't use cxx to test_libpf target") Signed-off-by: Stanislav Fomichev <sdf@google.com> Signed-off-by: Alexei Starovoitov <ast@kernel.org> Acked-by: Andrii Nakryiko <andriin@fb.com> Link: https://lore.kernel.org/bpf/20191202215931.248178-1-sdf@google.com
