I think it needs a good comment explaining this weirdness, at least.
As I said, if there is no DEBUG_INFO, there is not point in doing
DWARF-to-BTF conversion, even more -- it actually might fail, I
haven't checked what pahole does in that case. So I'd rather drop
GCC_PLUGIN_RANDSTRUCT is that's the issue here. DEBUG_INFO_SPLIT and
DEBUG_INFO_REDUCED look good.
