[qemu-s390x] [PULL 01/10] target/s390x: define TCG_GUEST_DEFAULT_MO for MTTCG |

From: Alex Bennée <address@hidden>
MTTCG should be enabled by default whenever the memory model allows
it. s390x was missing its definition of TCG_GUEST_DEFAULT_MO meaning
the user had to manually specify --accel tcg,thread=multi.
