Description Bernhard Wiedemann 2018-07-09 04:19:27 UTC 
While working on the reproducible builds effort, I found that
when building the glucat package for openSUSE Linux, there were slight differences between builds on different machines.

This is because g++ is invoked with the -march=native option
which means that depending on which OBS build worker machine gets the job
it might produce binaries unsuitable for older machines.
