Subject: config.host: Add driver-sparc.o and sparc/x-sparc on native
 sparc*-*-linux* builds.

	* config.host: Add driver-sparc.o and sparc/x-sparc on
	native sparc*-*-linux* builds.
	* config/sparc/driver-sparc.c: Correct Linux strings.
	* config/sparc/linux.h: Add DRIVER_SELF_SPECS.
	* config/sparc/linux64.h: Likewise.
	* doc/invoke.texi: Document that Linux also supports
	-mcpu=native and -mtune=native on sparc.
