I don't see the portability issue, since this patch doesn't actually try to
determine the number of CPUs.  Instead it's up to the user to set `build-cores'.
 But even if we would interpret `build-cores = 0' as "guess the number of CPUs",
it doesn't have to be perfect.  If it doesn't work on some platform, you can
always set the value manually.
