Simply take a look at ports that required /src or /sys to compile, eg.
lsof or fusefs-kmod:
lsof has: FREEBSD_SYS?= /usr/src/sys
fusefs-kmod has: SRC_BASE?= /usr/src
So neither of them use a predefined var.

Not quite sure on *when* you want to run make includes and if you want
to run it for the port or for /usr/src?
You could override the "pre-build:" target with stuff necessary pre

Not sure if they were helpful ...
