486 non-.got dynamic relocations.
487 (elf32_arm_size_dynamic_sections): Allocate .iplt, .igot.plt
488 and dynamic relocations for local STT_GNU_IFUNC symbols.

491 and use elf32_arm_allocate_irelocs to allocate them. Use stashed
492 section pointers intead of strcmp checks. Handle iplt and igotplt.
493 (elf32_arm_finish_dynamic_symbol): Use elf32_arm_populate_plt_entry
494 to fill in .plt, .got.plt and .rel(a).plt entries. Point
495 STT_GNU_IFUNC symbols at an .iplt entry if non-call relocations
497 (elf32_arm_output_plt_map_1): New function, split out from
498 elf32_arm_output_plt_map. Handle .iplt entries. Use
