kbuild: deb-pkg: split generating packaging and build
Move debian/ directory generation out of builddeb to a new script, mkdebian. The package build commands are kept in builddeb, which is now an internal command called from debian/rules. With these changes in place, we can now use dpkg-buildpackage from deb-pkg and bindeb-pkg removing need for handrolled source/changes generation. This patch is based on the criticism of the current state of builddeb discussed on: https://patchwork.kernel.org/patch/9656403/ Signed-off-by: Riku Voipio <riku.voipio@linaro.org> Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
