tfm: Build issues with some tests (posix, newlib)

[erwango]

Describe the bug

Build issues could be seen when building ns targets

See https://github.com/zephyrproject-rtos/zephyr/actions/runs/9709152909/job/26797411658?pr=74627

INFO    - 1) tests/posix/common/portability.posix.common.newlib on b_u585i_iot02a/stm32u585xx/ns error (Build failure)
INFO    - 2) tests/posix/common/portability.posix.common.tls.newlib on b_u585i_iot02a/stm32u585xx/ns error (Build failure)

INFO    - 1) tests/lib/c_lib/thrd/libraries.libc.c11_threads.newlib on b_u585i_iot02a/stm32u585xx/ns error (Build failure)
INFO    - 2) tests/lib/c_lib/thrd/libraries.libc.c11_threads.newlib_nano on b_u585i_iot02a/stm32u585xx/ns error (Build failure)

This is not specific to the board itself as the same errors could be seen with other ns target (nrf9160dk/nrf9160/ns for instance)

To Reproduce
west twister -p nrf9160dk/nrf9160/ns -s tests/lib/c_lib/thrd/libraries.libc.c11_threads.newlib

Expected behavior
Compilation ok.

Impact
Blocker

Logs and console output

`west twister -p nrf9160dk/nrf9160/ns -s tests/lib/c_lib/thrd/libraries.libc.c11_threads.newlib`
