PA-RISC also uses function descriptors. On HP-UX, for both PA-RISC and
IA-64, the e_entry field is the address of the code entry point itself,
rather than the address of a function descriptor. Our dynamic loader
initializes its own gp value, and when it's time for the dynamic loader
to call the application's entry point, it knows what the gp value should
be, so we don't need a function descriptor.
