I (painfully) found out that a similar problem occurs with 'make bindeb-pkg'.
After spending half a day unsuccessfully trying to debug and fix the problem I
ran across this patch. The naive approach of mimicking the solution and adding
'MAKE="$MAKE -f $srctree/Makefile"' at the top of scripts/package/builddeb
didn't work. Reverting commit 80463f1b7bf9 fixed the problem.
Would you be able to give it a look ? I'm afraid my limited skills related to
the kernel build system don't allow me to submit a fix :-S
