qemu: add wrapper for qemu-mips binary
qemu-mips user emulation binary segfaults when running any kind of
binary. This is due to a MMU access fault in the virtual CPU. This
problem has been introduced in qemu when 4GB of vmem were reserved for
32-on-64 bit.
This workaround will need to be reverted once the proper fix is found.
