So they can be checked with htl too.

-/* When one dynamically loads a module, which spawns a thread to perform some
-   activities, it could be possible that TLS storage is accessed for the first
-   time in that thread.  This results in an allocation request within the
-   thread, which could result in an attempt to take the rtld load_lock.  This
-   is a problem because it would then deadlock with the dlopen (which owns the
-   lock), if the main thread is waiting for the spawned thread to exit.  We can
-   at least ensure that this problem does not occur due to accesses within
-   libc.so, by marking TLS variables within libc.so as IE.  The problem of an
-   arbitrary variable being accessed and constructed within such a thread still
-   exists but this test case does not verify that.  */
