There's no way to build this using OE?...
Though, sure, it's should work as long as the binaries and kernel
modules actually loads and runs.

Could you check if any -dev packages gets installed into the image? If
so which one? Do anything like kernel-src or something similar gets
installed?

Are the source code packaged installed and packaged?
Can you inspect the generated package ${PN}, and see what it's depencies
are?

That would rather be in either local.conf, distro, or in your image.

I don't understand. Were the .debug directories located in
packages-split/<package-name>-dbg? If so, that's where we want them.
Which package do you add to your image?
If you remove that package, do you still get the kernel headers
installed?
