The kernels for Debian stretch require some special CFLAGS settings which are only correctly defined when NOSTDINC_FLAGS is set during the execution of the Makefile via kbuild. But batman-adv sets it currently outside to insert compatibility include headers and compat-sources. This can be avoided by making the top Makefile kbuild compatible and redefining the NOSTDINC_FLAGS when kbuild includes this Makefile. The actual build of the batman-adv module is then done by adding the subdirectory to obj-y.
