Fix arm-none-eabi-ld: warning: /github/workspace/sources/nuttx/nuttx has a LOAD segment with RWX permissions

Report from all ci console, like this:
https://github.com/apache/nuttx/actions/runs/7347758008/job/20004759931

Start by opening the linked GitHub Actions run and locating the arm-none-eabi-ld warning in the CI console. Trace the build or linker configuration that produces the NuttX image and determine how the RWX LOAD segment is introduced. Done means the affected CI builds complete without this warning, with relevant build validation recorded.
