When we generate code for guest loads and stores, at the moment they end up being requests for a host-endian access. So for target-system-nios2 (little endian) a load like ldw r3,0(r4) results on an x86 host in the TCG IR qemu_ld_a32_i32 r3,loc2,al+leul,0 but on s390 it is qemu_ld_a32_i32 r3,loc2,al+beul,0The result is that guests don't work on big-endian hosts. Use the MO_TE* memops rather than the plain ones.

It has been broken since initial commit: 032c76bc6f9 was already wrong. Reviewed-by: Richard Henderson <richard.hender...@linaro.org> r~
