Yeah, but it's a pain.  Here's a first pass that works for the common
case of reporting errors during a final link.  It would be possible to
flesh out _bfd_dwarf_get_relocated_section_contents with various bits
of code stolen from elflink.h in case finfo is not available, but that
could get tricky.  eg. If .debug is not going to be output, and thus
does not have an output_section, then how do you dig up the output bfd?
