The difference between the address of the original and the relocated _GLOBAL_OFFSET_TABLE_ is always the same as the relocation offset. The relocation offset is already computed and it is available in the 's1' register. Use that to adjust the relocated _G_O_T_ address, instead of calculating the offset again from the _gp value.
