Bug 20915: Do not initialize DTV of other threads.
In _dl_nothread_init_static_tls() and init_one_static_tls() we must not touch the DTV of other threads since we do not have ownership of them. The DTV need not be initialized at this point anyway since only LD/GD accesses will use them. If LD/GD accesses occur they will take care to initialize their own thread's DTV. Concurrency comments were removed from the patch since they need to be reworked along with a full description of DTV ownership and when it is or is not safe to modify these structures. Alexandre Oliva's original patch and discussion: https://sourceware.org/ml/libc-alpha/2016-09/msg00512.html
