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>

# Simple script to generate a deb package for a Linux kernel. All the
|
|
# complexity of what to do with a kernel after it is installed or removed
|
|
# is left to other scripts and packages: they can install scripts in the
|
|
# /etc/kernel/{pre,post}{inst,rm}.d/ directories (or an alternative location
|
|
# specified in KDEB_HOOKDIR) that will be called on package install and
|
|
# removal.
