* configure.in (--enable-deterministic-archives): Grok new

	argument.  Set DEFAULT_AR_DETERMINISTIC to 1 or 0 accordingly.
	* configure: Regenerated.
	* config.in: Regenerated.
	* ar.c (deterministic): Initialize to -1.
	(decode_options, ranlib_main): Grok U option.
	(usage, ranlib_usage): Mention U; say for D and U which is the default.
	(default_deterministic): New function.
	(ranlib_main): Call it.
	(main): Likewise.  Make newer_only && deterministic error
	non-fatal if it was just DEFAULT_AR_DETERMINISTIC and not the D option.
	* doc/binutils.texi (ar cmdline, ranlib): Document U modifier and
	--enable-deterministic-archives behavior.
