The tip gcc includes an optimization mode that converts 64-bit divides into 128-bit multiplies using __multi3. Export the symbol so that modules can find it. We just export unconditionally without worrying about the gcc version, since the symbol has been in libgcc forever and the function is less than 300 bytes.
