S/390: Fix (some) PIE+undef weak failures
This fixes these failures on 64 bit which currently occur when running
the Binutils testsuite with a default PIE compiler.
< FAIL: Build rdynamic-1
< FAIL: Build dynamic-1
< FAIL: Build pr22269-1
bfd/ChangeLog:
2017-12-13 Andreas Krebbel <krebbel@linux.vnet.ibm.com>
* elf64-s390.c (elf_s390_adjust_dynamic_symbol): Use
UNDEFWEAK_NO_DYNAMIC_RELOC.
(allocate_dynrelocs): Likewise.
(elf_s390_relocate_section): Check resolved_to_zero.
(elf_s390_finish_dynamic_symbol): Don't generate runtime reloc if
UNDEFWEAK_NO_DYNAMIC_RELOC.
