Subject: [C++] Add missing dependency on $(PARAMS_H)

When you add a new --param entry and rebuild an existing compiler, you get 
weird C++ regressions in the testsuite because of outdated object files.

Tested on x86_64-suse-linux, applied on the mainline as obvious.

	* Make-lang.in (cp/typeck.o): Add dependency on $(PARAMS_H).
	(cp/name-lookup.o): Likewise.
