as can be seen in #365349, debug info is also useful in other contexts, such
in my case, I would like to use the system tap interface; however, without

BTW: the ubuntu kernel guys already have built-in support for debug packages,
so in case their packages are related to yours, adding support may be trivial
(and quite helpful for the users).
