* elf-bfd.h (struct eh_cie_fde): Add need_relative and
need_lsda_relative. * elf-eh-frame.c (_bfd_elf_eh_frame_section_offset): Set need_relative or need_lsda_relative if we are processing an offset for a reloc on a FDE initial loc or LSDA field respectively. (_bfd_elf_write_section_eh_frame): Test need_relative and need_lsda_relative in place of corresponding make_* field when deciding to use pc-relative encodings.
