* 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.
