unit/test_auth fails on ppc64el, mips and mipsel
In Debian, I've cherry-picked the test suite on top of 4.1.0, and @unit/test_auth@ fails on 3 architectures:
- https://buildd.debian.org/status/fetch.php?pkg=libotr&arch=ppc64el&ver=4.1.0-3&stamp=1452773296
- https://buildd.debian.org/status/fetch.php?pkg=libotr&arch=mipsel&ver=4.1.0-3&stamp=1452773508
- https://buildd.debian.org/status/fetch.php?pkg=libotr&arch=mips&ver=4.1.0-3&stamp=1452773434
