branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master
libbpf does not support all architectures, for example ARM is not
supported resulting in the following build failure:
bpf.c:53:4: error: #error __NR_bpf not defined. libbpf does not support your arch.
# error __NR_bpf not defined. libbpf does not support your arch.
