    x86-64: Remove BND from 64-bit IBT PLT

    Since MPX support has been removed from x86-64 psABI, remove BND from
    64-bit IBT PLT by using x32 IBT PLT.

            * elf64-x86-64.c (elf_x86_64_get_synthetic_symtab): Also check
            x32 IBT PLT for 64-bit.
            (elf_x86_64_link_setup_gnu_properties): Always use x32 IBT PLT.
