QEMU isn't pure C code and effort would be required to make it run under
Native Client.

I've never used Native Client but I think its machine code verifier
checks the application to ensure that control flow is safe.  In other
words, low-level things that QEMU does like code generation or stack
switching are probably not allowed under Native Client since they are
unsafe!

Maybe I'm wrong and it's possible, but the first thing to check is the
constraints that Native Client puts on the application code.
