entries will need R_ARM_IRELATIVE relocations and use
elf32_arm_allocate_irelocs to allocate them. Likewise other
non-.got dynamic relocations.

from here...
(_bfd_sparc_elf_link_hash_table_create): ... to here. Allocate
local hash table.
(_bfd_sparc_elf_link_hash_table_free): New.
(create_ifunc_sections): New.
(_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
dyn relocs for ifunc.
(_bfd_sparc_elf_adjust_dynamic_symbol): Handle ifunc.
(allocate_dynrelocs): Unconditionally emit a PLT entry when STT_GNU_IFUNC
and h->def_regular. Count GOT dyn relocs for ifunc.
(allocate_local_dynrelocs): New function.
(_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.
(_bfd_sparc_elf_relocate_section): Handle ifunc relocations by hand.
(_bfd_sparc_elf_finish_dynamic_symbol): Adjust for non-dynamic ifunc plt
in iplt/irelplt.
ld/testsuite/
* ld-ifunc/ifunc.exp: Run for sparc.
