I don't think that would really work well. The qtests are build once for all targets, and HVF is only available in the target that matches the host architecture. It's poisoned on purpose.
The TCG accelerator is special, since we have it in either none or in all targets, that's why we can use CONFIG_TCG there.
The kvm part is also rather a hack... we should maybe rather additionally use the "query-kvm" QAPI command to check whether it is really available...?
To fix this properly for HVF, I think you'd need a way to query the available accelerators via QMP, too... Hmmm, weren't there some patches for something like that in the past ... can't remember right now ...
