commit d0329c1
Author: Dmitry Smirnov <onlyjob at member.fsf.org>
Date:   Mon Jul 27 00:17:16 2015

    Build with "-fPIC" and "--disable hardening" (Closes: #777983)
    
    "--disable hardening" prevents overriding build flags from the environment
    and fixes error:
    
        #error "You  must build your code with position independent code if Qt
        was built with -reduce-relocations."
        Compile your code with -fPIC (-fPIE is not enough).
