The main motivator of this series is to get the arm build fixed. 522667917 "lib: backtrace printing" added a common backtrace() function, but we missed that arm's __builtin_return_address only accepts the input 0, and thus the function, which calls it with all values 0 to 20, can't compile on arm. To fix backtrace() for arm, the easiest thing to do is to override it with a backtrace that works. So this series makes some cleanups to stack tracing support and adds the support for ARM.
