Subject: Remove duplication in binary dist rules
X-Git-Url: http://git.megacz.com/?p=ghc-hetmet.git;a=commitdiff_plain;h=410db5b555b74beb68aa39de950c2ca0e9c89f8e

Remove duplication in binary dist rules
Rather than building complex sh stuff and echoing what we're doing
ourselves, use make rules to do the looping and let make print things
out.
