* options.h (class General_options): Define -n/--nmagic and

	-N/--omagic.
	* options.cc (General_options::finalize): For -n/--nmagic or
	-N/--omagic, set -static.
	* layout.cc (Layout::attach_allocated_section_to_segment): If
	-N/--omagic, don't put read-only and read-write sections in
	different segments.
	(Layout::find_first_load_seg): If -N/--omagic, don't insist on
	finding a read-only segment.
	(Layout::set_segment_offsets): If -N/--omagic or -n/--nmagic,
	don't set the minimum segment alignment to the common page size,
	and don't set the file offset to the address modulo the page size.
	* script-sections.cc (Script_sections::create_segments): If
	-n/--omagic, don't put read-only and read-write sections in
	different segments.
