There is an article about that, it's reasonably recent (there is a 
walk-through using it on Debian 7.1) but it may not be plug-and-play. 
https://openwrt.org/docs/guide-user/virtualization/qemu#openwrt_in_qemu_x86-64

I don't know much about the topic myself, so I can't help much more than 
this.

If you try it and find issues please update the article if you can.
