Potential patch.
This hasn't been tested yet; when it has I can add a changelog and post it.
That's in progress now.
Ranjit's patch to enable prologue analysis on i386 changed the behavior for
other SJLJ targets. They used to call the no-op fallback_backtrace from
sysdep/generic/backtrace.h; afterwards they called _Unwind_Backtrace. This
links for SJLJ, but does not work, and when the trace function is called for
_URC_END_OF_STACK, _Unwind_GetIP segfaults.
