No they don't.  So far as I am aware the only point of putting a break
between the foundation and the wall is to prevent moisture migration from
the ground through the foundation and into the wall.  If you are building
a rock wall about one foot above grade, then that should provide an
adequate moisture break (assuming that you have provided adequate
perimeter drainage around the foundation).
