Replace relative long addressing instructions of weak symbols, which will definitely resolve to zero, with either a load address of 0, a NOP, or a trapping insn. This prevents the PC32DBL relocation from overflowing in case the binary will be loaded at 4GB or more. bfd/ChangeLog: * bfd/elf64-s390.c (elf_s390_relocate_section): Replace instructions using undefined weak symbols with relative addressing to avoid relocation overflows. ld/ChangeLog: * ld/testsuite/ld-s390/s390.exp: * ld/testsuite/ld-s390/8GB.ld: New test. * ld/testsuite/ld-s390/weakundef-1.dd: New test. * ld/testsuite/ld-s390/weakundef-1.s: New test.
