3.0: can't bootstrap on arm-linux

Digging into this a bit more, I think there is a typo in configure.in.

if AC_TRY_EVAL(ac_compile); then
  if grep _Unwind_Sjlj_Resume conftest.s >/dev/null 2>&1 ; then
    enable_sjlj_exceptions=yes
  elif grep _Unwind_Resume conftest.s >/dev/null 2>&1 ; then
    enable_sjlj_exceptions=no
  fi
fi

$ grep _Unwind_ conftest.s
        bl      _Unwind_SjLj_Register
        bl      _Unwind_SjLj_Resume
        bl      _Unwind_SjLj_Unregister
$

I find it slightly hard to believe that nobody has ever tested libjava on a 
target with sjlj exceptions before, but there you are.
