Subject: Define NO_TLS on ia64. The dynamic TLS implementation on ia64 is
 broken for non-threaded shared processes in that __tls_get_addr() assumes the
 thread pointer is always initialized. This is not the case. When arenas_map
 is referenced in choose_arena() and it is defined as a thread-local variable,
 it will result in a SIGSEGV.

PR: ia64/91846 (describes the TLS/ia64 bug).
