SubjectMakefile changes for kernel add-ons
I made the following changes to the kernel Makefile in order to
keep track of which kernel I am running, and also to allow
multiple module sets for add-ons which create modules that are
incompatible with a stock kernel (such as the pentium-memcpy).
With this patch in, I no longer need to recompile modules
or muck about with renaming module directories (which I often
forget) when making kernel changes. I can now boot any kernel
and not have to worry about which version the modules are
compiled for.

These give me the following UTS name and modules directory:
