This patch should help people who misunderstand the importance of using
proper prefixes to their ELF sections in bpf object files. The patch
assumes that programs with type BPF_PROG_TYPE_UNSPEC are always invalid,
as indicated by `man 2 bpf`. Please let me know if that is not accurate.

FYI, you don't need to send a cover letter with a single patch.
