[ Upstream commit 02826a6ba301b72461c3706e1cc66d5571cd327e ]
Ard Biesheuvel reports bindeb-pkg with O= option is broken in the following way:

Prior to commit 80463f1b7bf9 ("kbuild: add --include-dir flag only for out-of-tree build"), both srctree and objtree were added to --include-dir redundantly, and the wrong code '$MAKE image_name' was working by relying on that. Now, the potential issue that had previously been hidden just showed up.
'$MAKE image_name' recurses to the generated $(objtree)/Makefile and ends up with running in srctree, which is incorrect. It should be invoked with '-f $srctree/Makefile' (or KBUILD_SRC=) to be executed in objtree.
