After applying this patch:
$ ./install/bin/qemu-system-x86_64 -smp 12
cpu topology: error: sockets (1) * cores (1) * threads (1) < smp_cpus (12)
That is why I wanted to address the most obvious (and less risky) issues first
(aborting only if all options were explicitly set), and touch automatic
calculation later.
