Subject: [PATCH bpf-next 2/2] selftests: bpftool: skip the build test if not in tree

From: Jakub Kicinski <jakub.kicinski@...ronome.com>

If selftests are copied over to another machine/location
for execution the build test of bpftool will obviously
not work, since the sources are not copied.
Skip it if we can't find bpftool's Makefile.
