    * elf-ifunc.c (_bfd_elf_allocate_ifunc_dyn_relocs): Properly
    handle symbols marked with regular reference, but not non-GOT
    reference when building shared library.

    * elf32-i386.c (elf_i386_gc_sweep_hook): Properly handle
    local and global STT_GNU_IFUNC symols when building shared
    library.
    * elf64-x86-64.c (elf_x86_64_gc_sweep_hook): Likewise.
