I don't think we need to add it to the other function since we'll get an error anyway if the linker can't find the libraries. In any case, the right way to handle this is probably to error out in the driver before trying to compose a link job when `-flang-experimental-exec` is not specified, rather than rely on a specific linker error. But that should probably be a different patch. @awarzynski wdyt?
