    PR26907, segment contains empty SHT_NOBITS section

    Section ordering is important for _bfd_elf_map_sections_to_segments
    and assign_file_positions_for_load_sections, which are only prepared
    to handle sections in increasing LMA order.  When zero size sections
    are involved it is possible to have multiple sections at the same LMA.
    In that case the zero size sections must sort before any non-zero size
    sections regardless of their types.
