 292         to get the list of dynamic relocations for a local symbol.
 293         (elf32_arm_check_relocs): Always create ifunc sections.  Set isym
 294         at the same time as setting h.  Use elf32_arm_allocate_local_sym_info
 295         to allocate local symbol information.  Treat R_ARM_REL32 and
 296         R_ARM_REL32_NOI as call relocations in shared libraries and
 297         relocatable executables.  Record PLT information for local
 298         STT_GNU_IFUNC functions as well as global functions.   Count
 299         non-call PLT references.  Use elf32_arm_get_local_dynreloc_list
 300         to get the list of dynamic relocations for a local symbol.
