Thank you! The lone build failure appears to be unrelated and I've added #3578 to hopefully address it. (not that it matters, as running Python is a perfectly good alternative, but is the alternative shell command getconf _NPROCESSORS_ONLN portable?)

I tried this PR on a Mac and on a Linux system -- built Pyportal -- works OK for both. |

#3541 (396979a) breaks building on macOS, which doesn’t have an
nproccommand. That seems to be a Linux thing. The equivalent would besysctl -n hw.logicalcpu, but since I can’t find any existing platform distinctions in the makefiles, I chose to call Python for a cross-platform solution. (Credits to https://stackoverflow.com/questions/1715580.)
