  The kernels for Debian stretch require some special CFLAGS settings which
are only correctly defined when NOSTDINC_FLAGS is defined inside 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 include this Makefile. The actual
build of the batman-adv module is then done by adding the subdirectory to
obj-y.
