Fix powerpc64-linux inferior function calls

[David Lecomber]

Hi Dan,

I think this one arrived with your mega-change in September.  I've
binary searched it to the diffs you made on 2005-09-10:

 2005-09-10  Daniel Jacobowitz  <dan@codesourcery.com>
           Ulrich Weigand  <uweigand@de.ibm.com>

When debugging it, as I said before, I really didn't believe the output
from where ppp64_linux_convert_from_func_ptr_addr attempted to read from
the address of that function pointer.. (stack is after my .sig..) but
that is also the point at which my subject knowledge is exhausted.
