Rework the Linux drm kernel module build to leverage off the standard
kernel build system. This is based on suggestions and examples from David Woodhouse. This approach has the advantage that the build requirements of a wider range of standard kernels are now supported transparently, but the disadvantage of some extra complexity to handle building against clean vendor-distributed kernel source trees. This has been tested with some recent Red Hat and SuSE distributions.
