PR gas/3800

Browse Source 
* readelf.c: Include elf/h8.h twice.  The first time in order to get the reloc
  numbers, the second time in order to get the reloc decoder function.
  (dump_section): Tell the user if the section being displayed has unprocessed
  relocs associated with it.
  (get_reloc_size): New function - returns the size of a reloc.
  (debug_apply_rela_addends): Use get_reloc_size().
* dwarf.c (read_and_display_attr_value): Extend number of languages known for
  the DW_AT_language attribute.
  (process_debug_info): Display the attribute offset before decoding the
  attribute, in case there are problems.
