Define a set of functions that support the standard rules (build, install, test, *etc*). Then simply add new components and tools to the appropriate variable to support all the standard build semantics. Fixes #331. Signed-off-by: James O. D. Hunt <james.o.hunt@intel.com>

# - The component depends on its Makefile.
