s390: Add DT_JMPREL pointing to .rela.[i]plt with static-pie
In static-pie case, there are IRELATIVE-relocs in
.rela.iplt (htab->irelplt), which will later be grouped
to .rela.plt. On s390, the IRELATIVE relocations are
always located in .rela.iplt - even for non-static case.
Ensure that DT_JMPREL, DT_PLTRELA, DT_PLTRELASZ is added
to the dynamic section even if htab->srelplt->size == 0.
See _bfd_elf_add_dynamic_tags in bfd/elflink.c.
bfd/
elf64-s390.c (elf_s390_size_dynamic_sections):
Enforce DT_JMPREL via htab->elf.dt_jmprel_required.

s390: Avoid dynamic TLS relocs in PIE
No dynamic relocs are needed for TLS defined in an executable, the
TP relative offset is known at link time.

* elf64-s390.c (elf_s390_tls_transition): Use bfd_link_dll
instead of bfd_link_pic for TLS.
(elf_s390_check_relocs): Likewise.
(allocate_dynrelocs): Likewise.

IBM zSystems: Add support for z16 as CPU name.
So far z16 was identified as arch14. After the machine has been
announced we can now add the real name.

Without a -M cpu option given, powerpc objdump defaults currently to
-Mpower10 but -Many is also given. Commit 1ff6a3b8e562 regressed
-Many disassembly of instructions that are encoded differently
depending on cpu, such as mftb which has pre- and post-power4
encodings.

* ppc-dis.c (lookup_powerpc): Revert 2021-05-28 change. Instead
only look at deprecated PPC_OPCODE_RAW bit when -Many.
