Add preliminary native sparcv9 Solaris support.

	* configure.in: Recognize sparv9-*-solaris2*
	* configure: rebuilt
	* config.sub: Recognize sparcv9 just like sparc64.
	* config/sparc/sol2-c1.asm config/sparc/sol2-ci.asm
	config/sparc/sol2-cn.asm: Macroize so it can be shared between
	32-bit and 64-bit Solaris systems.
	* config/sparc/t-sol2: Assemble those with cpp.
	* config/sparc/sparc.h (TARGET_CPU_sparcv9): New alias for v9.
	(*TF*_LIBCALL): If ARCH64 use V9 names.
	* config/sparc/{xm-sysv4-64,sol2-sld-64}.h: New	files.
