I just tried another stm32 board on Linux(Ubuntu 22.04), thread aware
debugging works as expected:
1. make image:
```
./tools/configure.sh stm32f429i-disco:nsh
enable CONFIG_DEBUG_TCBINFO=y
CONFIG_TASK_NAME_SIZE=32
```
2. connect the jlink:
```
$ make -f Makefile.host jlink-nuttx.so
$ JLinkGDBServer -if SWD -device Cortex-M33 -rtos $PWD/jlink-nuttx.so
