That's all a bit silly. How come no-one noticed and told me how foolish
I am? We can't trash the arg registers willy-nilly.
I'm going for a stub at the end of the .plt, with .plt and .got guaranteed
to be glued together. The fixup fptr will be immediately after the stub
at the end of the .plt, ie. at got[-2] istead of got.
