+       * elf32-i386.c (elf_i386_link_hash_entry): Add
+       func_pointer_refcount.
+       (elf_i386_link_hash_newfunc): Clear func_pointer_refcount.
+       (elf_i386_get_local_sym_hash): Likewise.
+       (elf_i386_copy_indirect_symbol): Also copy
+       func_pointer_refcount.
+       (elf_i386_check_relocs): Increment func_pointer_refcount.
+       (elf_i386_gc_sweep_hook): Decrement func_pointer_refcount.
+       (elf_i386_allocate_dynrelocs): Don't create the PLT entry if
+       there are only function pointer relocations which can be
+       resolved at run-time.  Keep dynanamic relocations for run-time
+       function pointer initialization.
+       (elf_i386_relocate_section): Copy dynamic function pointer
+       relocations.
