Replacement for .if !target(${foo})

[Larry Owen]

Hello,
   First off, I'm not on list, so please include me 
in on the reply.  Does anyone have a clever way to 
recreate the following bsd make code with gnu make:

.for stage in pre post
.for name in download unpack patch configure \
             build install link package web

.if !target(${stage}-${name})
${stage}-${name}:
        @${DO_NOTHING}
.endif

.endfor
.endfor
