Linux Kernel build dpkg-buildpackage error

[Ewan Marshall]

Try `make -j $(getconf _NPROCESSORS_ONLN) bindeb-pkg LOCALVERSION=-custom`

Line 77 of scripts/Makefile.Package is:
`$ mv $(KDEB_SOURCENAME).tar.gz 
../$(KDEB_SOURCENAME)_$${origversion}.orig.tar.gz`

which suggests it is not finding the file $(KDEB_SOURCENAME).tar.gz 
debians instructions tell one to use the bindeb-pkg build target instead 
of deb-pkg build target for some reason. I can't see it not working 
unless there is another error before this you are not giving us.
