perf tests: Skip the llvm and bpf tests if HAVE_LIBBPF_SUPPORT isn't defined
If either NO_LIBBPF=1 is passed, explicitely disabling it or if libbpf is not available due to some missing dependency, skip its tests, telling the user the feature isn't available. # perf test <SNIP> 40: LLVM search and compile : Skip (not compiled in) 41: Session topology : Ok 42: BPF filter : Skip (not compiled in) <SNIP> Cc: Adrian Hunter <adrian.hunter@intel.com> Cc: Ian Rogers <irogers@google.com> Cc: Jiri Olsa <jolsa@kernel.org> Cc: Namhyung Kim <namhyung@kernel.org> Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
