One could use any bash variable.
I could have used :
This-is-my-setting-for-make-to-use-multiple-cores"-j $(getconf
_NPROCESSORS_ONLN)"
make ${This-is-my-setting-for-make-to-use-multiple-cores}
what you are looking for is make -j <some number>
I was daemonstrating a way to fetch the number of cores on the host system and
use that. Rather than "lets see should I use x number or cores on this build
host or y number of cores". The system under build just sets the number with
no fuss. No export needed
