Bug#877418: dh-strip-nondeterminism: kills clojure performance

Great stuff! So, we have two options as I see it:

  a) We patch clojure with ">="  (and send it upstream, etc. etc.)

  b) We make strip-nondetermism subtract 1 second from the .clj files'
     target modification times so it matches with the existing ">".

My preference is for "a)", naturally...

I was slightly scared we had broken Java performance throughout
Debian! *g*
