	entries should live in .plt or .iplt.  Check whether the .igot.plt
	and .got entries can be combined.  Use elf32_arm_allocate_plt_entry

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