I'm generally fine with being able to overwrite hang(), but the ARM
specific changes here should be an extra patch with an explanation why
this change is necessary. I assume you want to make hang() usable
for early debugging in the PBL when the code is not running at the
address it's linked at. But that's only an assumption.
