s390: Avoid reloc overflows on undefined weak symbols
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.
