* doc/binutils.texi: Add -D/--enable-deterministic-archives option

to strip and objcopy.
	* objcopy.c (deterministic): New global variable.
	(strip_options): Add --enable-deterministic-archives.
	(copy_options): Likewise.
	(copy_usage): Likewise.
	(strip_usage): Likewise.
	(copy_archive): When stripping all, don't add archive map; set
	deterministic output when requested.
	(strip_main): Add -D/--enable-deterministic-archives option.
	(copy_main): Likewise.
