The kernel module Makefile should support cross compilation

[GoogleCodeExporter]

The kernel module Makefile currently assumes that we are not doing cross 
compilation. This is silly as cross compilation is a frequent usage. Fix it.

I think this has been done (at least the Makefile pays attention to $(CROSS_COMPILE))
