Reclaim a bit of binsize on hdd based archoses by making the bit test unsigned. On SH1, gcc optimizes this by using a right shift, and a signed '1' made it use an arithmetic right-shift-by-n, which is a libgcc function on SH1. This was the only place in the core using it. No effect on other architectures.
