Your request sounds strange to me. If a project requires a specialized tool chain, I would consider it wrong to just silently fall back to something different as required. It is similar to the always re appearing discussion about 64bit libs. It is in the responsibility of the integrator to care for correct building of the targets, including using the correct tools, headers and libraries. And this often is a difficult task.
