I can't reproduce the problem here.  My tool chains are newer tho
(11.1).  Hmmm... I really don't see how calling a function or not can
cause relocation overflow in other places.  For the linker, all three
setup_pcpu functions aren't that different.

I'll set up a 11.0 system and see whether I can reproduce the problem.
Just in case, can you please try to rebuild after mrproper?
