Piotr says lscpu isn't available on ppc FreeBSD. I think this leaves us with
two options:
1. either use sysctl with the risk that it may not return an accurate value
2. not support PPC for numa detection
What do you think?
I think point #2 is more not supporting FreeBSD on PPC for numa dete

Hi,
sorry for the late answer.
I suppose you mean sysctl command, not systemctl.
On dual CPU systems, it returns 2. On single CPU ones, 1.

Add an option to automatically discover the host's numa and cpu counts
and use those values for a non cross-build.
Give users the option to override the per-arch default values or values
from cross files by specifying them on the command line with -Dmax_lcores
and -Dmax_numa_nodes.
