for  ChangeLog

	[BZ #19826]
	* elf/dl-tls.c (_dl_allocate_tls_init): Restore DTV early
	initialization of static TLS entries.
	* elf/dl-reloc.c (_dl_nothread_init_static_tls): Likewise.
	* nptl/allocatestack.c (init_one_static_tls): Likewise.


Alex is going to hand this patch off to me to champion and finish
iterating on with the rest of the interested developers (Andreas, Torvald,
Florian).

I'll work up a version 2 right now and post it shortly.

What's the status here? It seems that Alexandre committed it onSeptember 22nd, despite Torvald's objections.

This patch broke non-optimized global-dynamic TLS on aarch64 (for sharedbuilds), as shown by my new tst-tls-manydynamic test case.
