* elflink.h (size_dynamic_sections): If section named 

".preinit_array" exists, create DT_PREINIT_ARRAY and
        DT_PREINIT_ARRAYSZ entries in dynamic table.  Analogously for
        ".init_array" and ".fini_array".
        (elf_bfd_final_link): Handle DT_PREINIT_ARRAYSZ, DT_INIT_ARRAYSZ,
        DT_FINI_ARRAYSZ, DT_PREINIT_ARRAY, DT_INIT_ARRAY, and
        DT_FINI_ARRAY.
