Today's bug is a `libbpf` bug: https://lore.kernel.org/bpf/ZXcFRJVKbK[email protected]/

`bpftool` fails to recognize `BPF` programs. But it does it only when all of the below are true:

Error: failed to link 'bpf.o': Invalid argument (22)

With https://git.kernel.org/pub/scm/linux/kernel/git/bpf/bpf-next.git/commit/?id=32fa058398624166dd04ff4af49cfef69c94abbc

it now says

libbpf: ELF section #9 has inconsistent alignment addr=8 != d=4 in bpf.o
