I use GCC 13.2 personally, but the lower bound is what LLVM supports as it's built as a part of LLVM. This is somewhat out of scope since it's "technically" not supported but I got away with it since I happened to only touch a few files that were compatible (until this patch). Somewhat hacky so I apologize for the inconvenience. We're just hitting the intersection of what's really annoying to order with CMake and this was the easiest solution.

I think in the future I really want to move the RPC implementation out of `libc` so it's not locked down here. That would get rid of one thing and I could make sure that's compatible. The other remaining use of `libc` utilities would be the `file.h` wrappers for the GPU and the `printf` handling.
