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)
