Improve the functionality of the PORTS_MODULES knob by adding

Browse Source 
LOCALBASE/bin and sbin to PATH, allowing dependencies to be found;
adding SRC_BASE and OSVERSION to match the new kernel, and putting
the related builds under MAKEOBJDIRPREFIX so that they only need
to be built once per kernel.

In addition to the PR this includes ideas/contributions from crees
and matthew.
