* configure: Regenerated after aclocal.m4 change.

	* sysdeps/x86_64/sysdep.h [HAVE_ELF] (L): Define with .L##name form.
	* sysdeps/unix/sysv/linux/x86_64/sysdep.h (L): Don't define it here.

	* sysdeps/generic/dl-lookupcfg.h [USE_TLS] (DL_LOOKUP_RETURNS_MAP):
	Define it, because _dl_sym presumes it (for any platform).

	* sysdeps/x86_64/dl-tls.h: New file.

	* sysdeps/x86_64/dl-machine.h (elf_machine_rela): Add a cast.
