The present code breaks with a non-modular kernel. This can be easily avoided.

There were a couple of mistakes in this patch (which is fine, we allmake mistakes!), so I reverted it along with explanations:

What problem were you trying to solve, Ivan? What do you mean by“non-modular kernel”?
Thanks,Ludo’.

The intent was to allow a Linux package with CONFIG_MODULES=n to work after 5c79f238634c5adb6657f1b4b1bb4ddb8bb73ef1. There are no modules and no ‘lib/modules’.
Will you accept a patch that changes linux-module-database to skip unsuitable inputs instead?
