      kbuild: deb-pkg: fix bindeb-pkg breakage when O= is used · 02826a6b

      Ard Biesheuvel reports bindeb-pkg with O= option is broken in the
      following way:

      Prior to commit 80463f1b ("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.
