However, the linker will fail because of something in the kernel build process that I think produces empty sections, which that linker can't handle. A newer linker can handle it, but that's not scheduled to be released until much later this year. That's actually the closest option currently. I tried the upstream source but it seems to lack some specific patches to support kernel compilation, so I will need to chase those down.
