I think you guys are measuring two different things. One is linking an
ELF with debug info, which includes merging all the debug info. The
other is MachO, which always uses something like fission.

But that raises an interesting point: the overhead might be noticeable
when not using debug info or when using .dwo.

It seems fairly easy to add a warning. I will give it a try and send for
review.
