    Cygwin: automake: fix warning in terms of the `ps' target
    
    We are building a ps executable, but the rule to build the target
    collides with an auto-generated, documentation-related `ps' rule.
    
    Work around that by naming the executable "cygps" at build time
    and use a transform rule to rename it at installation time.
