It is just a build at this point. I have around 5 other PRs to make spirv stuff operational for offloading and I expect at least 2-3 more to get libc ready for testing with spirv. I can try to remove some of these but I am not sure what value it is going to bring at this point, given the fact that most of the code is not changed as part of the PR, but it carries some risk that some of this can be missed in the process of bringing it back.
