Marcus and Nick reported issue where BTF_ID macro generates same symbol in separate objects and that breaks final vmlinux link. Adding __LINE__ number suffix to make BTF_ID symbol more unique, which is not real fix, but it would help for now and meanwhile we can work on better solution as suggested by Andrii in [2].
