* elf32-i386.c (elf_i386_finish_dynamic_sections): Add output_offset

Browse Source 
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.
