Since commit 96d79976f779589 kvm-unit-tests can not be compiled on
s390x anymore. The compiler complains:
lib/s390x/io.c: In function ‘exit’:
lib/s390x/io.c:57:1: error: ‘noreturn’ function does return [-Werror]
Let's make sure that the function can really not return anymore
(i.e. also do not return anymore in case SIGP is broken for example).
