* subsegs.c (abs_seg_info, und_seg_info): Define if BFD_ASSEMBLER. 

(subseg_change): Store seg_info for bfd_abs_section_ptr in
	abs_seg_info, and store seg_info for bfd_und_section_ptr in
	und_seg_info.
	(subseg_get): Likewise.  Also, don't set output_section if it is
	already set.
	(seg_info): Define as function.
	* subsegs.h (seg_info): Declare as function rather than defining
	as macro.
	* write.c (relax_and_size_seg): Call seg_info rather than
	bfd_get_section_userdata.
