* 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.
