I did look into this a bit more and we need to make some kind of a decision here.

If we expect people building the cluster to install the headers with
headers_install then we can basically remove all the references to KERNEL_SRC in
all userland and everything will keep building just fine.

If we want to allow people to build the cluster with an outside kernel then we
need to fix or change the dirafter and change the Makefile's that use KERNEL_SRC
to be all consistent in the same way.

Given that we need KERNEL_SRC defined for the kernel modules that we carry
around in the CVS tree, I would suggest to go for the latter solution and allow
our users to build whatever they need.

I have patches ready for both cases so David, please let me know what you guys
would prefer.
