File a bug on objcopy? The best alternative I can imagine would be clang
running objcopy to check if it supports the flag and then producing some
other error message which seems like a workaround for an objcopy bug & a
lot of work for a relatively infrequent case (& no doubt there'll be a
stack overflow post with "why do I get this objcopy result when I enable
split-dwarf" with the appropriate answer of "upgrade objcopy to version
No-op by default seems misleading.
Error when it's not actually problem seems misleading too.
This produces errors when it's an error and makes it work when it works,
with the drawback of having a somewhat confusing failure mode.
