Current make doesn't have support to pass kernel built directory
to find events.h kernel header file, so adding support for
KBUILD_OUTPUT support to Makefile.

I can see where you are coming from, but wouldn't we normally expect the kernel
headers for the relevant kernel to available as part of the toolchain being
used to do the build?
They often lag a bit I guess, so perhaps we do want to put this little bit
of 'fudging' in place.
What do others think?

If it is a native build, we can expect toolchain to provide kernel
headers, but for a cross compile user has to provide where the kernel
headers present for the target which is done this patch.
