Description

The descriptions of each of the CI builds are hard to decipher without looking at the build scripts, which are themselves quite complex.

For example in this job: https://travis-ci.org/apache/arrow/jobs/346309532 you can see that the envars CC and CXX are set to "clang-5.0" and "clang+-5.0" respectively and they are then immediately set to gcc and g+.'

Without intimate knowledge of the script it's very hard to diagnose CI issues.
