Huh, ok.  But the spec seems to call it unconditionally in the 
link-command-spec when -g is visible.  At least I can't see how
a "source file" is matched (and we now definitely do find object
files as source for the link step).

And the issue is probably that we match on the intermediate link
command but execute only after that is finished.

Well, that dsymutil hack looks like a hack.
