From: Björn Töpel <bjorn.topel@xxxxxxxxx>
When libbpf was built was a shared library, libelf was not included in
the linking phase. Since libelf is an internal depedency to libbpf,
libeld should be included. This patch adds '-lelf' to resolve that.
Fixes: 1b76c13e4b36 ("bpf tools: Introduce 'bpf' library and add bpf feature check")
