Make and submakes have been gone over already. See <URL:

I'm not sure it can be applied to the ports tree, though. I haven't
looked into it, but recalled this paper when you mentioned measuring
makes and sub-makes.

Reducing the number of variables will certainly cut down on the amount
of overhead in the make/submake context switches by a long shot.
Maybe someone should consider running a 'pre-make' using the .mk files,
find the variables of interest for all particular sub-ports, and then
carry on the 'root make', i.e. make process in each port directory, with
just the variables of interest.
