Debian build fail.

Hi, I'm trying to cross-compile ROS2 for the RPI3 but it fail when is installling the ROS2 dependencies. This is the log:

`bash .`
2. Run the command below to export the environment variables used by the cross-compiled ROS packages.
`source .`'

If I execute locate inside of the docker, it returns that is POSIX instead of UTF-8, I don't know if this might be the problem.

I'm working with Ubuntu 18.04.

Hi jfm92,

I noticed that you're using debian for your cross compile target. Cross Compile currently only supports ubuntu for target image.

I have opened up an issue #81 to add support for Debian as a target.

I looked a bit into why this is failing: on a fresh Debian image, /etc/locale.gen has en_US.UTF-8 commented out.

I've open up a PR #82 to properly generate the en_US.UTF-8 locale.

Hi @jfm92 ,

Can you try this again using master? The following PRs were merged in:

• 82 fixes the locale-gen error you encountered

• 85 fixes later problems that arose when running ./test/run_e2e_test.sh --os debian

I just tried and now it works, thank you!
