The global pointer is used by some special assembly instructions that we are not using (i.e., the compiler is not generating them for us, because we don't use PIC or other "strange" stuff. So, we'd better remove an assignement in the linker script that makes little sense (it must be a typo of some kind, in the dark ages of this code base).
