commit 680af52f21391b45e365b15466fbe8e05a3043cf
Author: Mattia Rizzolo <mattia at debian.org>
Date:   Sat Jun 11 14:30:10 2016 +0100

    Build with -O2 on ppc64el to fix FTBFS
    
    Ubuntu defaults to -O3, which causes a leak to be detected in the test
    suite on ppc64el. Force -O2 instead (whilst still honouring noopt) as a
    workaround.
