Anas Nashif 33592e8aa8 cmake: remove IS_TEST handling Depending on a path inside the Zephyr tree to determine if we are a test does not scale. Also some samples were marked as TEST while they are not, just to get some options defined for tests. Idenitfying a test will be addressed in another patch introducing CONFIG_TEST.

Synchronization Sample
######################

Overview
********

A simple application that demonstrates basic sanity of the kernel.
Two threads (A and B) take turns printing a greeting message to the console,
and use sleep requests and semaphores to control the rate at which messages
are generated. This demonstrates that kernel scheduling, communication,
and timing are operating correctly.

Building and Running
********************

This project outputs to the console.  It can be built and executed
on QEMU as follows:

.. zephyr-app-commands::
   :zephyr-app: samples/synchronization
   :board: qemu_x86
   :goals: run
   :compact:

On the supported ARM MCUs the project can be built with the MPU and the Thread
Stack Guard feature enabled:

.. zephyr-app-commands::
   :zephyr-app: samples/synchronization
   :board: v2m_beetle
   :conf: prj_stack_guard.conf
   :goals: build flash
   :compact:
