We do generate them generically with no objcopy hack.

As far as the standard text here, IMO it was just there in case people didn't have an objcopy around or don't want to split it. I'm not sure why we would want the ability. That said, if we do I'd rather have it as dwarf5 without split-dwarf as an option rather than a -gsingle-file-split-dwarf option.
