No "real need" just the following ideas
 - Ease 'make dist' - see patch 07/22 from this series.
 - Gets things more obvious by prefixing the winsys header inclusions with
$(hw)/drm or sw/$(platform).
 - This is how the cool kids do it (radeon) :P

One could argue that ilo's approach is correct, and everyone else is
encouraged to follow, yet I'm taking the route of least resistance :)
