I'm not sure what the right thing to do about this would be -- is there a
portable way to check whether the -o option names a real filename or not? Is
your intent that neither .o nor .dwo is generated? Why use -gsplit-dwarf in
that case? I'm inclined to document this away. If you care, please clone this
into a new bug report.
