From: Jörg Sommer <[email protected]> The current do_package does not strip the kernel modules, if they are signed. Hence, the files in a release image stay very big and the debug information are not split into the kernel-dbg package.
The idea of this change is to suppress the signing of the modules on `modules_install` and run `modules_sign` after the debug information was striped.
