    IBM zSystems: Fix offset relative to static TLS
    
    For local exec TLS relocations of the form foo@NTPOFF+x the addend was
    ignored.
    
    bfd/ChangeLog:
    
            * elf32-s390.c (elf_s390_relocate_section): Honor addend for
            R_390_TLS_LE32.
            * elf64-s390.c (elf_s390_relocate_section): Honor addend for
            R_390_TLS_LE64.
    
    ld/ChangeLog:
    
            * testsuite/ld-s390/reloctlsle-1.d: New test.
            * testsuite/ld-s390/reloctlsle-1.s: New test.
    
    (cherry picked from commit aefebe82dc89711384b85329daa48d04c1d3a45b)
