Subject: [PATCH 3/3] Accepting request 499876 from
 home:bmwiedemann:branches:Base:System

Make build reproducible in spite of gcc profile based optimizations (boo#1040589)

The previous version would create an unused tar file called 'd'
and use an empty tmpfile for training gzip profiles
though it did make builds reproducible, it would lose some optimizations
