	* objcopy.c (deterministic): Make int rather than bfd_boolean,
	initialize to -1.
	(strip_options, copy_options): Add -U/--disable-deterministic-archives.
	(default_deterministic): New function.
	(strip_main, copy_main): Handle -U.  Call default_deterministic.
	(copy_usage, strip_usage): Describe -U.  Cite whether -D or -U is
	the default based on DEFAULT_AR_DETERMINISTIC.
	* doc/binutils.texi (objcopy, strip): Describe -U and effect of
	configure options on -D.

	* ar.c (default_deterministic): Comment fix.
