travis: drop support for Ubuntu Precise Ubuntu Precise is end of life since April 2017. At that point in time, Precise was still the main distro on which Travis CI built upon, with the Trusty-based images still being in a beta state. But since June 21st, Trusty has officially moved out of beta and is now the default image for all new builds. Right now, we build on both old and new images to assure we support both. Unfortunately, this leaves us with the highest minimum version for CMake being 2.8.7, as Precise has no greater version in its repositories. And because of this limitation, we cannot actually use object libraries in our build instructions. But considering Precise is end of life and Trusty is now the new default for Travis, we can and should drop support for this old and unmaintained distribution. And so we do.
