+Set the default thread-local storage (TLS) model to use for thread-local
+variables. Valid values are: "global-dynamic", "local-dynamic", "initial-exec"
+and "local-exec". The default is "global-dynamic". The default model can be
+overridden with the tls_model attribute. The compiler will try to choose a more
+efficient model if possible.
