--- Comment #4 from Dominik Vogt <vogt at linux dot vnet.ibm.com> ---
From <glibc>/sysdeps/s390/dl-tls.h:

  /* The special thing about the s390 TLS ABI is that we do not have the
  standard __tls_get_addr function but the __tls_get_offset function
  which differs in two important aspects:
  1) __tls_get_offset gets a got offset instead of a pointer to the
  tls_index structure
  2) __tls_get_offset returns the offset of the requested variable to
  the thread descriptor instead of a pointer to the variable.
  */

So, ist a NULL function called here because __tls_get_addr_internal does not
exist?
