* arm.cc: Replace "endianity" with "endianness" in comments.
	(Arm_exidx_cantunwind): Ditto.
	(Arm_relobj::Arm_relobj): Initialize merge_flags_and_attribures.
	(Arm_relobj::merge_flags_and_attributes): New method.
	(Arm_relobj::merge_flags_and_attributes_): New data member.
	(Arm_exidx_cantunwind::do_fixed_endian_write): Fix formatting.
	(Arm_relobj::scan_sections_for_stubs): Ditto.
	(Arm_relobj::do_read_symbols): Check to see if we really want to
	merge processor-specific flags and attributes.  Exit early if
	an object is empty except for section names and the undefined symbol.
	(Target_arm::do_finalize_sections): Move check for ELF format to
	Arm_relobj::do_read_symbols.  Merge processor specific flags and
	attributes from a regular object only when we have determined that
	it is aapropriate.  Do not create an .ARM.attributes section in
	output if there is no regular input object.
	(Target_arm::merge_processor_specific_flags): Check
	--warn-mismatch before printing any error.
	(Target_arm::merge_object_attributes): Ditto.
	* gold.cc (queue_middle_tasks): Handle the case in which there is
	no regular object in input.
	* options.cc (General_options::parse_EB): New method.
	(General_options::parse_EL): Same.
	(General_options::General_options): Initialize endianness_.
	* options.h (-EB, -EL, -no-pipeline-knowledge, -p, --warn-mismatch):
	New options.
	(General_options::Endianness): New enum.
	(General_options::endianness): New method.
	(General_options::endianness_): New data member.
	* parameters.cc (Parameters::set_options): Check target endianness.
	(Parameters::set_target_once): Ditto.
	(Parameters::check_target_endianness): New method.
	(parameters_force_valid_target): If either -EL or -EB is specified,
	use it to define endianness of default target.
	* parameters.h (Parameters::check_target_endianness): New method
	declaration.
	* target.h (class Target): Change "endianity" to "endianness"
	in comments.
