Cross compiling kernel modules for distro kernels is not supported in debian.
To simplify downstream kernel module builds, we automatically turn off cross
compilation for a user-provided module when building it for a distro kernel.
This patch further replaces the hard-coded list of distro kernels with
the DISTRO_KERNELS variable to avoid code duplication.

What do we do if this changes one day, in trixie e.g? Or is even fixed

We can simply add more logic to this python function. As of today, it
is broken for all debian versions. And in general it should not hurt
(except for performance) to emulate the compile.
Well... I know that currently modules for custom kernels MUST be cross
compiled as well if the custom kernel was cross compiled. But this is a
different story and Stefan is working on it.

Hi,
asking again as the release is now done. Can we get that integrated, or
do I need rework something?
