* options.cc (options::help): Print list of supported targets.

	* target-select.h: Include <vector>.
	(class Target_selector): Make machine_, size_, and is_big_endian_
	fields const.  Add bfd_name_ and instantiated_target_ fields.
	(Target_selector::Target_selector): Add bfd_name parameter.
	(Target_selector::recognize): Make non-virtual, call
	do_recognize.
	(Target_selector::recognize_by_name): Make non-virtual, call
	do_recognize_by_name.
	(Target_selector::supported_names): New function.
	(Target_selector::bfd_name): New function.
	(Target_selector::do_instantiate_target): New pure virtual
	function.
	(Target_selector::do_recognize): New virtual function.
	(Target_selector::do_recognize_by_name): New virtual function.
	(Target_selector::instantiate_target): New private function.
	(supported_target_names): Declare.
	* target-select.cc (Target_selector::Target_selector): Update for
	new parameter and fields.
	(select_target_by_name): Check that the name matches before
	calling recognize_by_name.
	(supported_target_names): New function.
	* i386.cc (class Target_selector_i386): Update Target_selector
	constructor call.  Remove recognize and recognize_by_name.  Add
	do_instantiate_target.
	* x86_64.cc (class Target_selector_x86_64): Likewise.
