[Bug 1473674] [NEW] apt fails a test from the testsuite on ppc64el when built with gcc-5 and -O3

[Matthias Klose]

Public bug reported:

to reproduce:

 - wily chroot
 - PPA https://launchpad.net/~ci-train-ppa-service/+archive/ubuntu/landing-016/
   (this holds gcc-5 as the default, branch 20150711).
 - dpkg-buildpackage -B 

note that explicitly using the gcc-5/g++-5 from wily doesn't show the
test failure. the only difference in the configuration is that the one
in wily is built using the old libstdc++ ABI and the one in the PPA with
the dual ABI defaulting to new/c++11.

building with -O2 instead of -O3 works around the issue.
