Just to follow up on this, the closest thing right now to compile the kernel for Hexagon is the toolchain included with the Hexagon SDK. 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.
