* elf32-i386.c (elf_i386_finish_dynamic_sections): Add output_offset
to DT_JMPREL. Use srelplt input section size for DT_PLTRELSZ and
DT_RELSZ adjustment, not output section. Avoid writing tags when
unchanged. Don't assume linker script is sane, adjust DT_REL too.
* elf32-hppa.c (elf32_hppa_finish_dynamic_sections): Just use raw
size of srelplt for DT_PLTRELSZ. Use srelplt input section size for
DT_RELASZ adjustment, not output section. Avoid writing tags when
unchanged. Adjust DT_RELA.
* elf64-ppc.c (ppc64_elf_finish_dynamic_sections): Tweaks for better
formatting. Avoid writing tags when unchanged. Adjust DT_RELA.
