This problem seems to be caused by a endian issue in qemu-mips.  Ed
Maste found the culprit and I've applied it here:

https://github.com/seanbruno/qemu/commit/05ee8495804599b52a88eb36b13ea9c06b3207cd

Which is my combined tracking branch for qemu and sson's bsd-user
branch.

I'm currently tracking an "illegal instruction" on exit issue that seems
to happen on application exit causing a crash.
