nvidia display driver failure at do_package task for tegra234

[ichergui]

Using Jetson Orin AGX with wip-jetpack-5-dp

I removed the line KERNEL_SPLIT_MODULES = "0" to generate packages for each kernel modules (nvidia, nvidia-drm, nvidia-modeset)

I got the following error logs:

@kekiefer @madisongh This discussion is created to keep track of this issue.

We have workaround to avoid issues during debug-splitting that's messing up the debug symbols of the .ko files. Thanks @madisongh for that.

Since this smelled like a binutils bug, I tried with the newer binutils on master, but ran into the same issue

Thanks @kekiefer for doing that
