config.gcc (sparc*-*-*): Always set need_64bit_hwint to yes.

gcc/

	* config.gcc (sparc*-*-*): Always set need_64bit_hwint to yes.
	(sparc*-*-linux*): Use linux.h in tm_file.
	(sparc-*-linux*): If 'enabled_targets' is 'all', build a bi-arch
	compiler defaulting to 32-bit.
	(sparc*-*-*): Remove explicit target settings of need_64bit_hwint,
	no longer needed.
	* config/sparc/linux.h: Remove definitions now obtained
	properly from linux.h
	* config/sparc/linux64.h: Likewise.
	(ASM_CPU_DEFAULT_SPEC): Change this to ASM_CPU64_DEFAULT_SPEC, we
	don't want this setting for 32-bit builds in a biarch compiler.
	* doc/install.texi: Add sparc-linux to list of targets
	supporting --enable-targets=all.

libcpp/

	* configure.ac (sparc*-*-*): Always set need_64bit_hwint to yes.
	* configure: Regenerate.
