Extend the assembler so that it can automatically generate GNU Build attribute notes if none are present in the input files.
gas * as.c (flag_generate_build_notes): New variable.
(show_usage): Add entry for --generate-missing-build-notes.
(parse_args): Parse --generate-missing-build-notes.
* as.h: Export flag_generate_build_notes.
* symbols.c (save_symbol_name): Ensure that the name parameter is
not NULL.
* write.c (create_obj_attrs_section): Reformat.
(create_note_reloc): New function - creates a relocation for a
field in a GNU Build attribute note.
(maybe_generate_build_notes): New function - created GNU Build
attribute notes if none are present in the output file.
(write_object_file): Call maybe_generate_build_notes.
* configure.ac (--enable-generate-build-notes): New option.
* NEWS: Announce the new feature.
* doc/as.textinfo: Document the new option.
* config.in: Regenerate.
* configure: Regenerate.
binutils* readelf.c (is_32bit_abs_reloc): Support R_PARISC_DIR32 as a
32-bit absolute reloc for the HPPA target.
* testsuite/binutils-all/note-5.d: New test.
* testsuite/binutils-all/note-5.s: Source file for new test.
* testsuite/binutils-all/objcopy.exp: Run new test.
