	Fix the PCL fix, *sigh*
	... don't error if we can't find the class at macroexpand time,
		but emit a diagnostic instead.  (caught by McCLIM code)
	Also enhancement to make-target-contrib.sh
	... allow contribs to depend asdfwise on each other
	... (side effect: now ASDF-hooked REQUIRE works on fresh-built
		uninstalled SBCL with the command line:
	SBCL_HOME=`pwd`/contrib ./src/runtime/sbcl --core output/sbcl.core
	)
