    x86: Treat relocation against IFUNC symbol as FUNC

    When resolving a relocation against IFUNC symbol in a SHT_NOTE section
    without SHF_ALLOC, we treat it as relocation against FUNC symbol since
    it needs the address of IFUNC symbol, not the address returned by IFUNC
    function.

        PR ld/22929
        * elf32-i386.c (elf_i386_relocate_section): Treat relocation
        against IFUNC symbol in SHT_NOTE section without SHF_ALLOC as
        relocation against FUNC symbol.
        * elf64-x86-64.c (elf_x86_64_relocate_section): Likewise.
