Add stamp files for f/str-*

I find it a bit tedious that when I modify libiberty, several parts of
the Fortran compiler are rebuilt.  This happens because fini depends
upon libiberty, and str-*.[hj] depend upon fini.

This patch fixes that by using stamp files for f/str-*.[hj].

Note that we don't have to add the new files to f77.mostlyclean
because the top level mostlyclean target already deletes */stamp-*.

OK for mainline?

	* Make-lang.in (f/str-*.h, f/str-*.j): Use stamp files and
	move-if-change to avoid changing these files unnecessarily.
