To go along with Kyle's suggestion, I set my MAKEFLAGS with a file in
/etc/profile.d/ directory (I call it make-export.sh), so it is
automatically applied when any user logs in.

The following will set MAKEFLAGS to the number of CPU threads + 1 (it says
cores, but Linux the number of threads the CPU is capable of as individual
cores).

jbhansen at craven-moorhead:~$ cat /etc/profile.d/make-export.sh
#!/bin/bash

# Set make jobs to default to num cores + 1
export MAKEFLAGS="-j$(expr $(nproc) + 1)"
