Well, it makes perfect sense, since we select kvm first on macOS and, I guess,
all non-Linux platforms ;-)

% ./x86_64-softmmu/qemu-system-x86_64   
qemu-system-x86_64: invalid accelerator kvm
qemu-system-x86_64: falling back to tcg

(Fixing that knowing that CONFIG_KVM is poisoned in vl.c is left as an
exercise for the reader)
