Installation script issues

[benjamin0]

I tried to set up piksi_firmware using

sudo bash setup.sh -x install

The script doesn't throw any errors, but it looks like Ansible and therefore gcc-arm-none-eabi aren't installed correctly, because make fails.

After manually installing Ansible, wget, and cmake I tried to manually run the commands in tasks/arm.yml to install gcc-arm-none-eabi.

The "Add arm-gcc directory to PATH" step fails because in bash appending "\n" appends the characters "\n" and not a newline. In zsh this command works as intended.

After manually installing gcc-arm-none-eabi, the firmware successfully builds.
