__T222b___XDL_1/a-except.adb:1635: undefined reference to ` _Unwind_RaiseException'

Looking at a-except.adb, I see it has been changed from that
in the 3.2 branch to directly call _Unwind_RaiseException.
However, this routine is not available when using SJLJ
exceptions.

As ada builds sucessfully on the port using the 3.2 branch
with SJLJ exceptions, this would appear to be a regression.
