Build fail for Cortex-R5F

Dieses Issue hat noch niemand übernommen.

## Issue template

- Hardware description: Cortex R5F, ARM v7-R
- RTOS: FreeRTOS
- Installation type: micro_ros_setup
- Version or commit hash: humble

#### Steps to reproduce the issue
``
mkdir microros_ws && cd microros_ws
git clone -b humble https://github.com/micro-ROS/micro_ros_setup.git src/micro_ros_setup
rosdep update && rosdep install --from-paths src --ignore-src -y
colcon build
source install/local_setup.bash
ros2 run micro_ros_setup create_firmware_ws.sh generate_lib
touch my_custom_toolchain.cmake
touch my_custom_colcon.meta
ros2 run micro_ros_setup build_firmware.sh
``
#### Expected behavior
Firmware should build creating static libraries and required header files inside firmware/build/libmicroros.a and firmware/build/include
#### Actual behavior
[actual_output.txt.txt](https://github.com/micro-ROS/micro_ros_setup/files/14111855/actual_output.txt.txt)

#### Additional information
attaching my custom toolchain cmake and my custom colcon meta file
[my_custom_toolchain.cmake.txt](https://github.com/micro-ROS/micro_ros_setup/files/14111879/my_custom_toolchain.cmake.txt)
[my_custom_colcon.meta.txt](https://github.com/micro-ROS/micro_ros_setup/files/14111882/my_custom_colcon.meta.txt)
I tried removing the optimization flags in my_custom_toolchain.cmake file when I searched about it, but issue still remains

Beginne mit build_firmware.sh und reproduziere den colcon build mit my_custom_toolchain.cmake und my_custom_colcon.meta; untersuche actual_output.txt.txt auf den Fehler. Als erledigt gilt die Aufgabe, wenn der Firmware-Build für Cortex-R5F abgeschlossen wird und firmware/build/libmicroros.a sowie firmware/build/include erzeugt.
