* elf-eh-frame.c (_bfd_elf_eh_frame_section_offset): Add "info"
parameter. If called after _bfd_elf_write_section_eh_frame,
don't allow a -2 return unless need_* bit is already set, and
handle offsets adjusted for output_offset.
* elf-bfd.h (_bfd_elf_eh_frame_section_offset): Update prototype.
* elf.c (_bfd_elf_section_offset): Update call.
