On ARM EABI, Linux GNUEABI the standard unwind tables are part of the ABI, sjlj
exceptions are not used and are likely to be completely bit rotten. There is
not much chance that this will work by default on ARM and neither is it going
to be standard configuration. Given this situation and that there is no
interest in this option on ARM I'm going to reject this bug.
