As a first step we just need to know what we tell gcc or the linker to do, and what is incorrectly output. Once the problem is understood we can think about how to deal with the problem. What we really need is a recipe for success. A recipe for failure. At that point it should be much easier for someone else to reproduce the problem, and/or look into the specific details and see what is wrong or to suggest patches. The kernel is a significant enough program and a different enough one it is hard to predict how things go.
