I always thought that this was an accident waiting to happen, the South end of the runway has very little "run-off" area.
What utter rubbish! Check out the "run-off" areas at most airports and you'll notice a lot less than that. My own local airport (with B747 operations) is no better than that which Accra offers - and with a shorter runway. The bottom line is that if you plonk the a/c down where you should there's no problem. If you don't touch down by the required point then go around.
