* elflink.c (elf_bfd_final_link): Don't output STT_SECTION symbol
into .dynsym if elf_section_data (sec)->dynindx <= 0.
Adjust counting of last_local.

other than SHT_PROGBITS/SHT_NOBITS and neither for .got/.got.plt/.plt
created by the linker nor !SHF_ALLOC.
* elf32-i386.c (elf_i386_finish_dynamic_sections): Point
DT_PLTGOT to the start of the .got.plt section instead of the
.got output section. Set sh_entsize for .got section in addition
to .got.plt.
(elf_i386_relocate_section): Don't assume _GLOBAL_OFFSET_TABLE_
is at sgot->output_section->vma.
* elf64-x86-64.c (elf64_x86_64_finish_dynamic_sections): Point
DT_PLTGOT to the start of the .got.plt section instead of the
.got output section.
(elf64_x86_64_relocate_section): Don't assume _GLOBAL_OFFSET_TABLE_
is at sgot->output_section->vma. Set sh_entsize for .got section
in addition to .got.plt.
