This isn't the right solution.  The RiscPC bus does not support half-word
load/stores, so we must continue to build that target for the 32v3
architecture (which is why I carefully left that stuff behind.)

The mistake is in what I did with arch/arm/lib - the armv3 code in there
needs to be resurected instead.
