Hi Leonard,

This was a regression caused by r35275. Sorry for the inconvenience - it
only showed up if you had the ARM target enabled and not the Hexagon
target, due to the help options appearing in those two, so I didn't
discover it myself as I have all targets enabled. I temporarily reverted it
earlier (r352848), and I've got a fix for it about to go up for review in
