Add Darwin options from specs to darwin.opt

[Joseph S. Myers]

In preparation for the driver only accepting options listed in .opt
files, and not other options that simply happen to match some spec,
this patch adds Darwin options matched by specs to darwin.opt.  In the
case of -headerpad_max_install_names, the spec had a trailing '*' but
the Darwin ld manpage did not indicate the option took any operands,
so I removed the '*' from the spec.

Tested building cc1 and xgcc for cross to i686-darwin.  OK to commit?

	* config/darwin.opt (dylinker, headerpad_max_install_names,
	keep_private_externs, nofixprebinding, nomultidefs, noprebind,
	noseglinkedit, object, prebind, prebind_all_twolevel_modules,
	preload, private_bundle, pthread, seglinkedit, twolevel_namespace,
	twolevel_namespace_hints, whatsloaded, whyload, y, Mach, X): New
	Driver options.
	* config/darwin.h (LINK_SPEC): Remove '*' after
	headerpad_max_install_names.
