libbpf: add libelf dependency to shared library build
The DPDK project is moving forward with its AF_XDP PMD, and during that process some libbpf issues surfaced [1]: When libbpf was built as a shared library, libelf was not included in the linking phase. Since libelf is an internal depedency to libbpf, libelf should be included. This patch adds '-lelf' to resolve that. [1] https://patches.dpdk.org/patch/50704/#93571 Fixes: 1b76c13e4b36 ("bpf tools: Introduce 'bpf' library and add bpf feature check") Suggested-by: Luca Boccassi <bluca@debian.org> Signed-off-by: Björn Töpel <bjorn.topel@intel.com> Signed-off-by: Daniel Borkmann <daniel@iogearbox.net>
