cmake -E env: unknown option '-Wno-unique_unit_address_if_enabled'

[nandojve]

Describe the bug
The #31960 introduced the pre_dt_board.cmake file in many boards. The new rules add EXTRA_DTC_FLAGS "-Wno-unique_unit_address_if_enabled" to build system. This rules if not proper defined will break make menuconfig.

To Reproduce
Steps to reproduce the behavior:

1. cd samples/hello_world
2. west build -b atsamr21_xpro
3. west build -t menuconfig
4. See error

Expected behavior
west build -t menuconfig should never be broken by any change in Zephyr configuration.

Impact
It is not possible configure Zephyr without rollback.

Logs and console output

-- west build: running target menuconfig
...
cmake -E env: unknown option '-Wno-unique_unit_address_if_enabled'
...

Environment (please complete the following information):

• OS: Linux
• Toolchain Zephyr SDK sdk-0.12.3
• Commit #mainline

Additional context
It is expected a test that can check broken Kconfig options
