I believe that for Java, you must use sjlj eh unless there is either
some platform-specific code to turn signals into NullPointerExceptions,
or you have -fcheck-references enabled.
For dwarf2 exceptions the hard part seems to be unwinding the signal
handling frame. For a raw embedded target I guess that problem might not
exist since you may be able to avoid setting up the signal frame in the
first place?
