For the sake of discussion, what are the benefits of adding
btf__parse_opts(), compared to modifying btf__parse() to check if
.BTF.base is present and acting accordingly?
btf__parse() already does a guess if passed argument is an ELF or a
RAW file, so such guessing semantics seems to be a natural extension.
