uncovering some interesting problems. Be conservative and effecitvely disable this by default. Interested parties may still define KERNBUILDDIR by hand to achive the same effect. I plan on referting this change after 5.2 is released, or sooner if the issues with building releases are resolved and re@ approves. Approved by: re@ (scottl, marcel)
