add_fde_encoding. Remove need_relative. * elf-eh-frame.c (extra_augmentation_string_bytes) (extra_augmentation_data_bytes, size_of_output_cie_fde): New functions. (_bfd_elf_discard_section_eh_frame): Consider changing the FDE encoding in cases where the CIE has no existing 'R' augmentation. Use size_of_output_cie_fde when assigning offsets. Use the final offset as the new section size. (_bfd_elf_eh_frame_section_offset): Remove need_relative handling. Account for any extra augmentation bytes in the returned offset. (_bfd_elf_write_section_eh_frame): Rework so that the entries are moved before being modified. Pad growing entries with DW_CFA_nops. Add 'z' and 'R' augmentations as directed by add_augmentation_size and add_fde_encoding.
