264 STT_GNU_IFUNC functions as well as global functions. Count
265 non-call PLT references. Use elf32_arm_get_local_dynreloc_list
266 to get the list of dynamic relocations for a local symbol.

285 STT_GNU_IFUNC symbols at an .iplt entry if non-call relocations
286 resolve to it.
287 (elf32_arm_output_plt_map_1): New function, split out from
