a) sizeof_headers in link script
   -> program_header_size unknown, so get_program_header_size
      estimates two headers

b) _bfd_elf_map_sections_to_segments figures we need zero headers.
   -> lay out sections again.
   -> sizeof_headers again needed, and zero in program_header_size is
     taken as uninitialized value, so go to (a).
