Forgive me if I'm misunderstanding, but I think that listing qemu in
Kconfig may be desirable to me even if only user emulation is
supported. I currently run a set of regression tests as a post-build
step. I use qemu user emulation mode for this. Right now, I use a
system-installed version of qemu-arm but would prefer to use a
buildroot version.

I'm glad to see these patches come in. Thanks for adding them.
