+ARM is the only architecture that has a helper function that returns
+an unbiased result. This fix is trivial enough that we can show it
+doesn't effect any of the other arches. Can we consider this a
+regression fix since it used to work until the helper was added :}
+
+Tested with no regressions on x86_64-pc-linux-gnu and arm-none-eabi.
