                   ^^
If you pasted exactly what you have then there is a typo above it
should be SRC_URI_append_class-native ...

I can find a number of recipes that depend in one way or another on 'qemu-native', but I can't find a recipe, class for it or anything that provides it. I can see it being built, and I get an error that indicates that the patch that I have needs to be applied. I can find tmp/work/x86_64-linux/qemu-native/.
