Having a mix of tabs and spaces makes the diff of any changes to the build system noisier than necessary. This commit unifies them to two spaces. This includes some minor cosmetic changes such as with joining things on one line where appropriate. There are other files in libclc which have tabs but those haven't been touched at this time. Those could come at another time if desired, though they might be more contentious as the project isn't clang-formatted at all and so that might invite larger discussions around formatting.
