New version of qemu does not support MIPS host anymore.

For the sake of portability, the new version of qemu uses TCG, a tiny code generator, instead of dyngen to generate host code. That means one backend is needed for each host architecture. There are i386,x86_64,ppc,ppc64 and hppa backend in TCG, but MIPS is not on the list.

I confirm this conclusion on the status page of qemu web site. The MIPS's status is 'Not Supported'. Perhaps these days the most emergent work is to add MIPS host support, instead of loongson guest support to qemu.
