Many times it would be nice to quickly package up a kernel tree you're
working on, without having to rebuild the whole thing again from a clean
source tree (like the current rpm-pkg target does).  The patch below
adds an "binrpm-pkg" target which uses your existing (already built)
tree.
Modified by me to always do a make and use binrpm-pkg.
