docker: debian-bootstrap.pre allow customising of variant/url
We default to the buildd variant as most of our images are for building. However lets give the user the ability to specify "minbase" if they want to create a simple base image for experimentation. Allowing the tweaking of DEB_URL means we can also bootstrap other Debian based OS's. For example: make docker-binfmt-image-debian-ubuntu-bionic-arm64 \ DEB_ARCH=arm64 DEB_TYPE=bionic \ DEB_VARIANT=minbase DEB_URL=http://ports.ubuntu.com/ \ EXECUTABLE=./aarch64-linux-user/qemu-aarch64 Signed-off-by: Alex Bennée <alex.bennee@linaro.org> Reviewed-by: Philippe Mathieu-Daudé <f4bug@amsat.org> Tested-by: Philippe Mathieu-Daudé <f4bug@amsat.org>
