natSystem.cc (init_properties): Don't set user.name or user.home if NO_GETUID defined.

	* java/lang/natSystem.cc (init_properties): Don't set user.name or
	user.home if NO_GETUID defined.  Only set user.dir if getcwd
	exists.

	* include/config.h.in: Rebuilt.
	* acconfig.h (NO_GETUID): New define.
	* configure.in: Rebuilt.
	* configure.in: Define NO_GETUID in cross case.  Check for getcwd
	in native case.
