this patch didn't help to fix the broken deb-pkg for me:

../scripts/Makefile.build:44: ../../scripts/package/Makefile: No such
file or directory
make[2]: *** No rule to make target `../../scripts/package/Makefile'.  Stop.
make[1]: *** [deb-pkg] Error 2

steps to reproduce:
$ export KBUILD_OUTPUT=/make it out of src tree
$ make deb-pkg
