Ok, there is no full Clang toolchain, as we have zero EasyConfigs for those. I Can however instatiate a Clang toolchain similar to how it's done here https://github.com/easybuilders/easybuild-easyblocks/blob/b436f55669e5e09fe49555c7ce6a3c456dbacc4a/easybuild/easyblocks/c/clang.py#L420 . That 'prepare_rpath_wrappers()' call would cause an error without the fix in this current PR
