Don't generate PLT for IFUNC GOT/pointer reference
If a backend supports it, PLT entry isn't needed when all references to a STT_GNU_IFUNC symbols are done via GOT or static function pointers. For GOT entries, We generate dynamic R_*_GLOB_DAT relocations for preemptable symbols and R_*_IRELATIVE relocations for non-preemptable symbols to update them with real function address. For static pointer pointers, we generate dynamic pointer relocations and store them in: 1. .rel[a].ifunc section in PIC object. 2. .rel[a].got section in dynamic executable. 3. .rel[a].iplt section in static executable. We don't allocate GOT entry if it isn't used. bfd/ PR ld/20253 * elf-bfd.h (_bfd_elf_allocate_ifunc_dyn_relocs): Add an bfd_boolean argument. * elf-ifunc.c (_bfd_elf_create_ifunc_sections): Replace "shared object" with "PIC object" in comments.
