From: Johannes Schindelin
When Git v2.9.1 was released, it had a bug that showed only on Windows
and on 32-bit systems: our assumption that `unsigned long` can hold
64-bit values turned out to be wrong.
This could have been caught earlier if we had a Continuous Testing
set up that includes a build and test run on 32-bit Linux.
Let's do this (and take care of the Windows build later). This patch
asks Travis CI to install a Docker image with 32-bit libraries and then
goes on to build and test Git using this 32-bit setup.

Hi,
changes based on reviews since v2:
- removed "set -e"
- pass docker image name to run-linux32-build script
- use Dscho's docker run formatting
other changes:
- We run "make" with "-j2" and "make test" without parallelization because
prove already parallelizes the tests (see GIT_PROVE_OPTS in .travis.yml).
- If the tests fail then I make all output files readable to everyone.
This is necessary because the files are created with a root account
inside the docker container and I want to allow the "after_failure" step
outside the container to read the files without root permissions.
The job passes on the current master:
https://travis-ci.org/larsxschneider/git/jobs/207168867 (JS)
https://api.travis-ci.org/jobs/207168867/log.txt?deansi=true (non-JS)
The job fails on v2.9.1:
https://travis-ci.org/larsxschneider/git/jobs/207306002 (JS)
https://api.travis-ci.org/jobs/207306002/log.txt?deansi=true (non-JS)
Cheers,
Lars
