Adding custom message to Teensy micro-ROS using the docker image fails

Nobody has claimed this yet.

## Issue template

- Hardware description: Teensy 4.1
- RTOS: N/A
- Installation type: VM running ubuntu 22.04. ROS2 iron, micro ROS 2.0.7, Arduino IDE 2.2.1, Teensy Board version 1.57.2 (the latest did not work for me). running zsh.
- Version or commit hash: iron

#### Steps to reproduce the issue
Following the procedures: `https://github.com/micro-ROS/micro_ros_arduino/tree/iron#how-to-build-the-precompiled-library` to add a custom message to the system and recompile the library.
I get this step:
`docker run -it --rm -v /home/mgeppert/Arduino/libraries/micro_ros_arduino-2.0.7-iron:/project --env MICROROS_LIBRARY_FOLDER=extras microros/micro_ros_static_library_builder:iron -p teensy4`

#### Expected behavior
The build to be clean and useable in the Arduino IDE

#### Actual behavior
The image runs to the following point:

```

#### Additional information
This is my first experience with Docker and don't know how to find out what it is trying to do.
Prior to creating the custom messages things where working well. So the static libraries seem to work well for what I was testing.
The Host ROS Agent sees the new message correctly and compiled just fine.

I have tried to run the docker command both as non sudo and sudo. I even sudo su and tried to run it. Same errors.

Start with the documented “How to build the precompiled library” procedure and reproduce the Docker command for `teensy4`. Inspect why `/uros_ws/gcc-arm-none-eabi-5_4-2016q3/bin/arm-none-eabi-gcc` is unavailable and why `/project/src/` is incomplete. Done means the custom-message build completes and produces `firmware/build/include/` and `firmware/build/libmicroros.a` for Arduino IDE use.
