commit 23db183cbf6e669da66626996de7c2bdcdee9180
Author: Christian Kellner <christian at kellner.me>
Date:   Thu Jun 12 16:55:28 2014 +0200

    Add addBuildOpt helper function for building option string
    
    addBuildOpt should be called with the build option which is NOT
    surrounded by spaces since it will add spaces to separate options
    itself, if necessary.
