With this stack, I'm able to build world and the GENERIC kernel for riscv64 using riscv64-gcc15. I will test some other versions of GCC as well.

Thanks a lot for handling this.

As I recall from previous experiments building with GCC, there was some missing atomic libcall, or something? Maybe this has resolved itself?

That eventually got resolved in GCC (it kept causing issues in the Linux world too)
