This bit of Bill's patch did it:

-#ifdef HAVE_GAS_HIDDEN
+
+#if !defined(ENABLE_LLVM) && defined(HAVE_GAS_HIDDEN)
  fprintf (asm_out_file, "\t.%s\t", type);
  assemble_name (asm_out_file, name);
  fprintf (asm_out_file, "\n");
#else
  warning (OPT_Wattributes, "visibility attribute not supported "
           "in this configuration; ignored");
#endif
