target/nios2 : Explicitly ask for target-endian loads and stores
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,0
The result is that guests don't work on big-endian hosts.
Use the MO_TE* memops rather than the plain ones.
