Cross-compilation is much more hassle than native, especially with GCC. It's feasible for individual apps, but I would not want to set that up for an entire Linux distro.
Sure, but a new architecture is big risk reward. I expect the first companies to start selling consumer risc-v products will have a big budget to set up a datacenter, to remotely flash racks of their devices and run automated tests as their big team develops the risc-v linux distro it will run. Perhaps a nintendo switch 3? Samsung smartphone? Quallcomm smart toaster? Who knows. But it will probably be some big company on https://riscv.org/members/ who has an axe to grind with ARMs licencing fees, and is willing to go to this hassle.
Your comment seemed to be claiming that cross-compiling an entire operating system was infeasible. My comment was that it's exactly what big companies do.
