Subject: libbpf distro packaging

I would like to bring up libbpf publishing discussion started at [1].
The present state of things is that libbpf is built from kernel tree, e.g. [2]
For Debian and [3] for Fedora whereas the better way would be having a
package built from github mirror. The advantages of the latter:
- Consistent, ABI matching versioning across distros
- The mirror has integration tests
- No need in kernel tree to build a package
- Changes can be merged directly to github w/o waiting them to be merged
through bpf-next -> net-next -> main
There is a PR introducing a libbpf.spec which can be used as a starting point: [4]
Any comments regarding the spec itself can be posted there.
In the future it may be used as a source of truth.
Please consider switching libbpf packaging to the github mirror instead
of the kernel tree.
Thanks
