I have a project using NCS v1.8.0 where I enabled openthread.
For some reason, when trying to build `mbedtls/library/ecjpake.c`, the make command uses `-DMBEDTLS_CONFIG_FILE=\"nrf-config.h\"` and fails on:
> nrf-config.h: No such file or directory
I'm not sure why it tries to use this file because `MBEDTLS_CFG_FILE` is set to `config-tls-generic.h`.
Here is my defconfig:
```
CONFIG_GPIO=y
CONFIG_PM_DEVICE=y
CONFIG_NUM_METAIRQ_PRIORITIES=0
CONFIG_SYSTEM_WORKQUEUE_STACK_SIZE=1024
CONFIG_MAIN_STACK_SIZE=1024

CONFIG_OPENTHREAD_MTD=y
CONFIG_OPENTHREAD_MTD_SED=y
```
and the full error:
```
