Subject[PATCH] kbuild: add --include-dir flag only for out-of-tree build
Date
The --include-dir flag is used to include check-in Makefiles from
$(objtree) without prefixing $(srctree)/ the paths. Obviously, this
is unnecessary for in-tree build. Add the flag just before changing
the working directory.
