	* elf/rtld.c (_dl_start): Pass zero to TLS_INIT_TP.  Set
	bootstrap_map.l_tls_tp_initialized to 1 if TLS_INIT_TP was called.
	(_dl_start_final): Copy l_tls_tp_initialized to GL(dl_rtld_map).
	(dl_main): If HAVE___THREAD is not defined pass l_tls_tp_initialized
	to TL_INIT_TP.  Otherwise pass 1.
	* include/link.h (struct link_map): Add l_tls_tp_initialized.
	* sysdeps/generic/libc-tls.c (__libc_setup_tls): Pass 0 to TL_INIT_TP.

	* manual/contrib.texi: Removed licenses, added acknowledgements
	for contributions by Intel, IBM, Craig Metz.
	* LICENSES: New file, contains the text of all non-FSF licenses in the

	new one modelled on the modern BSD license, per recent letter
	of permission from CMU.

	* sysdeps/ieee754/dbl-64/MathLib.h: Changed the copyright holder
	from IBM to FSF, per the recent Software Letter.  Changed the
	distribution terms from GPL to LGPL.
