[PATCH] framestate.c breaks when gcc is compiled with --enable-sjlj-exceptions

Possible solution, tested on x86, hppa and alpha, no regressions.

I attempted to test a solution where "abort()" is used as the fallback
function if unwind-dw2.c does not provide anything. This didn't work
because we still need _Unwind_GetDataRelBase, _Unwind_GetTextRelBase, 
and _Unwind_GetRegionStart.

	* sysdeps/generic/unwind-dw2.c: Remove #ifndef
	__USING_SJLJ_EXCEPTIONS__ so compat code is always included.
