* We would like __dso_handle to be:
*   1. A const so that if a DSO does not have any RW data, .data section can
*      be omitted.
*   2. Of type void* so that no awkward type conversion is needed when
*      &__dso_handle is passed to various functions, which all expect a void*.
* To achieve both, we do the following aliasing trick.
