Actually I prefer only doing it in the parent.  Otherwise as these
things become more portable over time (e.g. when amd64 came along and
gained i386 linux compat), there may be many ports that are now
buildable but are forgotten until someone hunts down each and every
one of them and makes lots of fixup commits.
