* ruby.c (ruby_init_loadpath_safe): use real path for non-shared
	  build.
	* configure.in (LIBRUBY_RELATIVE): use rpath token expansion.
	* tool/rbinstall.rb (bin-comm): prepend prolog shell script if
	  necessary.
	* ruby.c (ruby_init_loadpath_safe): relatively called non-shared
	  binary cannot be found in PATH, so use given pathname.
