Yes, see https://libc.llvm.org/gpu/building.html. You likely don't need to be able to successfully run the tests, follow the CMake options to set a default test architecture and make sure you have the `llvm-gpu-loader` utility. That should build if you have the LLVM libc enabled.

Just build it targeting AMD (you need lld) and set the test architecture to gfx1030 or something. If you actually have an AMD GPU you should just need ROCm installed.
