	* tls.m4 (GCC_CHECK_CC_TLS): New.

libgcc/

2007-07-06  H.J. Lu  <hongjiu.lu@intel.com>

	* config.host (tmake_file): Add t-tls for i[34567]86-*-linux*
	and x86_64-*-linux*.

	* config/t-tls: New file.

	* Makefile.in (INTERNAL_CFLAGS): Add @set_have_cc_tls@. 

	* configure.ac: Include ../config/enable.m4 and
	../config/tls.m4.  Use GCC_CHECK_CC_TLS to check if assembler
	supports TLS and substitute set_have_cc_tls.
	* configure: Regenerated.

	Updated from Intel BID library:
	* bid_conf.h (BID_THREAD): Defined only if both HAVE_CC_TLS
	and USE_TLS are defined.
