Subject: [PATCH] travis: add Trusty with clang stable build
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Although we've reduced the matrix to avoid repeating clang builds we can
still add an additional clang build to use the latest stable version of
clang which will typically be available on current distros.
