You should avoid scripts if possible. You can use `enabled-by:  STM32H7_ERRATA_ENABLE_FMC_282` and make it an option with these actions:
```yaml
actions:
- get-string: null
- split: null
- env-append: ABI_FLAGS
```
You can also use a single `STM32H7_ERRATA_FMC_282_FLAGS` option which is `-mno-unaligned-access` by default and can be configured to be empty.

The libc, C++ library, etc. will not use this option. I am not sure if this is an issue.
