prepall: don't operate on ${ED} when it doesn't exist

prepall* funcs operate exclusively on ${ED}, which needs not to exist
when nothing is installed, such as e.g. with virtuals.  Refraining from
operating when ${ED} does not exist avoids error messages from find that
${ED} does not exist, bug #368839
