    PR 33852 Different objects for same input
    
    Testcase:
    $ cat aff.s
     .quad x@ntpoff
    $ gas/as-new -m64 aff.s -o t.o
    with MALLOC_PERTURB_ this reliably shows uninitialised memory making
    its way into the output.
    
    R_390_TLS_LE64 howto was sized incorrectly, resulting in the
    initialisation in s390_elf_cons zeroing only the first four bytes.
    
            * elf64-s390.c (elf_howto_table <R_390_TLS_LE64>): Correct
            size and bitsize.
