XStormy16 is using SJLJ.  And from the today's perspective I'm glad that
it hasn't been converted to DW2 EH, given the obvious problem with the
definition of the .eh_frame section.

There's also the problem that the .eh_frame section is rather big, and
that the section has to be loaded for EH to work.  This is not a
terribly good idea for a very space constricted target like XStormy16.
