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.
