Add build assert to make sure _RETARGETABLE_LOCKING is enabled in
toolchain, When _RETARGETABLE_LOCKING is enabled, "_LOCK_T" is "__lock"
pointer type, otherwise "_LOCK_T" is "int" type, so there will be the
following compile warnings when toolchain doesn't enable
_RETARGETABLE_LOCKING:
zephyr/lib/libc/newlib/libc-hooks.c:416:13: warning: cast to pointer from
integer of different size [-Wint-to-pointer-cast]
416 | k_sem_take((struct k_sem *)lock, K_FOREVER);
| ^
zephyr/lib/libc/newlib/libc-hooks.c: In function '__retarget_lock_acquire
_recursive':
zephyr/lib/libc/newlib/libc-hooks.c:423:15: warning: cast to pointer from
integer of different size [-Wint-to-pointer-cast]
423 | k_mutex_lock((struct k_mutex *)lock, K_FOREVER);
| ^
