non-hackish fix, fixed



oops, that was indeed casting pointers to size_t and back :)

This fixes it by working with offsets from the base of the malloc block.



I would be very careful with swapping because the size of the

arm_local_iplt_info* is unknown (could be 64-bit or anything). It would still

work, but just by accident, because we would allocate 2*num_syms of 32-bit

objects first, making sure the 64-bit pointers that follow are aligned. So I

strongly prefer the manual alignment approach; it's unlikely that a small

change in the code would break it.
