If we go this route, it seems like we should make it modifiable by 
distro layers. Currently, the qemuboot.conf settings live in OE-core, so 
I did not find a way to override the settings in a distro file. When I 
tried manually changing them, the setting did not take effect because 
the setting in OE-core got parsed last.

That said, I think it would be more ideal to make sure the settings work 
by default everywhere, without each layer having to tweak anything. As 
long as the compiled and runtime features match, I think we can achieve 
this goal.

To test the patch, I did:

git clone git://git.yoctoproject.org/poky
source oe-init-build-env
# manually edit MACHINE to be qemux86 or qemux86-64
bitbake core-image-minimal

I hit the initial bug when building AGL (Automotive Grade Linux), which 
pulls in meta-qt5, which surfaced the issue.

Sorry, adding oe-core now.
