Oops, that's right.  How about:
  /* We don't need to do anything unless:
     - Some debug information was recorded via .file/.loc
     - or, we are generating DWARF2 information ourself (--gdwarf2)
     - or, there is a user-provided .debug_info section which could
       reference the file table in the .debug_line section we generate
       below.  */
  if (all_segs == NULL
      && debug_type != DEBUG_DWARF2
      && )

Where the bit after the last && is "there is no user .debug_info"
section (which I can't figure out how to say in gas).
