	* elf-bfd.h (eh_cie_fde): Remove need_lsda_relative.
	Move make_lsda_relative to u.cie.
	* elf-eh-frame.c (cie): Rename make_lsda_relative to
	can_make_lsda_relative.
	(_bfd_elf_parse_eh_frame): Don't set the old eh_cie_fde
	make_lsda_relative field.  Update after cie renaming.
	Set u.cie.make_lsda_relative if can_make_lsda_relative
	and if we find a relocation against the LSDA.
	(_bfd_elf_discard_section_eh_frame): Copy make_lsda_relative when
	changing a CIE's group representative.
	(_bfd_elf_eh_frame_section_offset): Don't set need_ldsa_relative here.
	(_bfd_elf_write_section_eh_frame): Check u.cie.make_lsda_relative
	rather than need_lsda_relative.
