This looks to be misleading. ld goes through the motions of adding 
elements to the search path, including, it seems, printing out the above, 
but the library is not added to the search path. Notice that this 
function because a no-op if "cmdline" is true, and -nostdlib is set:

void
ldfile_add_library_path (name, cmdline)
     const char *name;
     boolean cmdline;
{
  search_dirs_type *new;
                                                                                                                            
  if (!cmdline && config.only_cmd_line_lib_dirs)
    return;
                                                                                                                            
  new = (search_dirs_type *) xmalloc (sizeof (search_dirs_type));
  new->next = NULL;
  new->name = name;
  new->cmdline = cmdline;
  *search_tail_ptr = new;
  search_tail_ptr = &new->next;
}
