Cosmic Cuttlefish test rebuilds

[Matthias Klose]

The first test rebuild of Cosmic Cuttlefish was started on September 11 2018 for
all architectures, all components (main component and seeded packages finished,
unseeded packages still building).  The number of build time failures
unfortunately is again high.

The test rebuild was done using the openjdk-11 packages from the openjdk-r/ppa
PPA (cosmic still has OpenJDK-10, instead of the OpenJDK-11 packages used for
the rebuild.

Results (please also look at the superseded builds) can be found at

http://people.canonical.com/~doko/ftbfs-report/test-rebuild-20180911-cosmic.html

The report uses some additional color coding, marking packages different which
always failed to build, or where the build failure is no regression compared to
bionic.

Additional build failures for packages in bionic-proposed (not yet in bionic)
can be found at http://qa.ubuntuwire.com/ftbfs/

Please help fixing the build failures.
