Subject: Remove move-if-change dependencies
Howdy,

Per

 http://gcc.gnu.org/ml/gcc/2004-02/msg00151.html

Make rules that use move-if-change should not depend on it.  The
following patch removes such dependencies.  It was bootstrapped
and regression tested on powerpc-unknown-linux-gnu.

OK to commit?

	(s-peep, s-attr, s-attrtab, s-output, s-genrtl, s-modes)
