    s390: Check sreldynrelro in elf_s390_finish_dynamic_symbol
    
    Add check for sreldynrelro being NULL, introduced by commit 5474d94f03ae
    ("dynrelro section for read-only dynamic symbols copied into
    executable") in elf32-s390.c function elf_s390_finish_dynamic_symbol,
    also to its elf64-s390.c counterpart.
    
    Found while inspecting and cleaning up differences between elf32-s390.c
    and elf64-s390.c.
    
    bfd/
            * elf64-s390.c (elf_s390_finish_dynamic_symbol): Add
            sreldynrelro check from elf32-s390.c.
    
    Fixes: 5474d94f03ae ("dynrelro section for read-only dynamic symbols copied into executable")
