Support distinct project and library makefile includes.
Makefile
makefiles/include.mk
makefiles/lint/include.mk
makefiles/python/include.mk
---------------------------
O Library makefiles only require an include directory var.
o Project makefiles require two vars, one for derived paths (TOP=).
o Infer library makefile path from the included makefile.
o Maintain MAKEDIR= and ONF_MAKEDIR= so caller can selectively
include what they want to use.
