[PATCH] kbuild: build a single module using 'make dir/module.ko'

Using the syntax: make dir/module.ko kbuild now allows one to build a module including the final link stage. This is usefull when one only wants to compile a single module and thus do not have to wait until a full kernel has finished compiling.
