Title:
  libceres-dev Focal arm64 build failing with failed test

Status in ceres-solver package in Ubuntu:
  Fix Released
Status in ceres-solver source package in Focal:
  Confirmed
Status in ceres-solver source package in Groovy:
  Fix Released

Bug description:
  [Impact]

  * ceres-solver's binary packages are not available on arm64 in Ubuntu
  Focal

  * tests seem to be failing on arm64:
  https://launchpad.net/ubuntu/+source/ceres-
  solver/1.14.0-4ubuntu1/+build/19091179

  * libceres is critical for robotics SLAM applications on Ubuntu, and
  arm64 is a very popular architecture for robotics

  [Test Case]

  * Simply run the existing test cases on arm64 and you'll see
  evaluation_callback_test fail just like in the above log

  [Regression Potential]

  * libceres isn't on arm64 at all, so the regression potential there is
  nil

  * This is a test-only change, thus the only regression possible on
  other architectures is that the tests don't pass and the package
  doesn't build as a result (although note that tests pass locally just
  fine on amd64)
