Add support for generating and inserting build IDs into COFF binaries.

	* peXXigen.c (pe_print_debugdata): New function: Displays the
	contents of the debug directory and decodes codeview entries.
	(_bfd_XXi_swap_debugdir_in, _bfd_XXi_swap_debugdir_out)
	(_bfd_XXi_slurp_codeview_record, _bfd_XXi_write_codeview_record):
	Add functions for reading and writing debugdir and codeview
	records.
	* libpei.h (_bfd_XXi_swap_debugdir_in, _bfd_XXi_swap_debugdir_out)
	(_bfd_XXi_write_codeview_record): Add prototypes and macros.
	* libcoff-in.h (pe_tdata): Add build-id data.
	* libcoff.h: Regenerate.
	* coffcode.h (coff_write_object_contents): Run build_id
	after_write_object_contents hook.

	* pe.h (external_IMAGE_DEBUG_DIRECTORY, _CV_INFO_PDB70)
	(_CV_INFO_PDB20): Add structures and constants for debug directory
	and codeview records.
	* internal.h (internal_IMAGE_DEBUG_DIRECTORY, CODEVIEW_INFO):
	Add structures and constants for internal representation of debug
	directory and codeview records.

	* emultempl/elf32.em (id_note_section_size, read_hex, write_build_id):
	Move code for parsing build-id option and calculating the build-id to...
	* ldbuildid.c: New file.
	* ldbuildid.h: New file.
	* Makefile.am (CFILES, HFILES, OFILES, ld_new_SOURCES): Add new
	files.
	* Makefile.in: Regenerate.
	* ld.texinfo: Update --build-id description to mention COFF
	support.
	* NEWS: Mention support for COFF build ids.
	* emultempl/pe.em (gld${EMULATION_NAME}_handle_option):
	(pecoff_checksum_contents, write_build_id, setup_build_id)
	(gld_${EMULATION_NAME}_after_open):  Handle and implement
	build-id option.
	* emultempl/pep.em: Likewise.
