That all looks good!

One question: is -j1 equivalent in all cases to no -j at all?

Another: for instances where people disapprove of -j, and / or where -j 
can't be used, would it be worth considering the parallel building of 
dependencies where the dependencies don't have interdependencies 
themselves?
