This complements and reuses logic from Andreas Krebbel's commit
896a639babe2 ("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 or a
a trapping insn.
This prevents the PLT32DBL relocation from overflowing in case the
binary will be loaded at 4GB or more.
bfd/
* elf64-s390.c (elf_s390_relocate_section): Replace
instructions using undefined weak symbols with relative
addressing to avoid relocation overflows.
ld/
* testsuite/ld-s390/s390.exp: Add new test.
* testsuite/ld-s390/weakundef-2.s: New test.
* testsuite/ld-s390/weakundef-2.dd: Likewise.
