Very good question. It seems to be just a damn big wall. There's a carpark on the other side of it. I've just been trying to find out if it was ever a part of a building, but it seems to have been just a wall even in the earliest pictures that I've found. I've asked the question on https://www.railforums.co.uk/
Edit: And the answer is that the station roof used to be much more extensive than it is now, the wall supported it along one side. It was removed in about 1955. This is what the station looked like in 1928:
