sol2.h (ASM_DECLARE_OBJECT_NAME): New. 

* config/sparc/sol2.h (ASM_DECLARE_OBJECT_NAME): New.  Emit
	"tls_object" for thread-local objects.
	* config/sparc/sparc.c (sparc_elf_asm_named_section): Emit
	"#tls" for thread-local sections.
	* configure.ac (thread-local checks): Specify --fatal-warnings in
	every binutils-specific checks.  For sparc*-*-*, test whether the
	OS is Solaris and the tools are native and act accordingly.
	* configure: Rebuild.
