PR introducing 0.0.5 ABI was merged:
https://github.com/libbpf/libbpf/commit/476e158
Jiri, you'd like to avoid patching, you can start w/ 0.0.5.
Also if you're planning to use *.spec from libbpf as a source of truth,
It may be enhanced by syncing spec and ABI versions, similar to
https://github.com/libbpf/libbpf/commit/d60f568
