	(_bfd_sparc_elf_check_relocs): Unconditionally assign htab->elf.dynobj
	and call create_ifunc_sections().  For local STT_GNU_IFUNC symbols
	cons up a fake local hash table entry for it.  Unconditionally add
	a PLT refcount for STT_GNU_IFUNC symbols when h->def_regular.  Count

	(_bfd_sparc_elf_size_dynamic_sections): Invoke it over the local hash table.
	Emit dynamic relocs to irelplt when not shared.  Treat iplt like splt.
