At least with my system-arm-linux.adb sjlj exceptions do not work
better than ZCX (I get jump to the top level handler and no proper
exception propagation), do you have a copy of a working one?

I'm putting in Cc Julian Brown who did the gcc/objc/exception.c
ARM EABI work (thanks to Andrew Pinsiki for the hint). I don't
have the technical expertise to do this work but I can
try suggestions and follow general directions (like I did for Ada
multilib with Paolo Bonzini).
