-Crosstool-NG (Deprecated)
-#########################
-
-.. warning::
-
-   ``xtools`` toolchain variant is deprecated. The
-   :ref:`cross-compile toolchain variant <other_x_compilers>` should be used
-   when using a custom toolchain built with Crosstool-NG.
-
-You can build toolchains from source code using crosstool-NG.
-
-#. Follow the steps on the crosstool-NG website to `prepare your host
-   <http://crosstool-ng.github.io/docs/os-setup/>`_.
-
-#. Follow the `Zephyr SDK with Crosstool NG instructions
-   <https://github.com/zephyrproject-rtos/sdk-ng/blob/master/README.md>`_ to
-   build your toolchain. Repeat as necessary to build toolchains for multiple
-   target architectures.
-
-   You will need to clone the ``sdk-ng`` repo and run the following command:
-
-   .. code-block:: console
-
-      ./go.sh <arch>
-
-   .. note::
-
-      Currently, only i586 and Arm toolchain builds are verified.
-
-#. :ref:`Set these environment variables <env_vars>`:
-
-   - Set :envvar:`ZEPHYR_TOOLCHAIN_VARIANT` to ``xtools``.
-   - Set :envvar:`XTOOLS_TOOLCHAIN_PATH` to the toolchain build directory.
-
-#. To check that you have set these variables correctly in your current
-   environment, follow these example shell sessions (the
-   :envvar:`XTOOLS_TOOLCHAIN_PATH` values may be different on your system):
-
-   .. code-block:: console
-
-      # Linux, macOS:
-      $ echo $ZEPHYR_TOOLCHAIN_VARIANT
-      xtools
-      $ echo $XTOOLS_TOOLCHAIN_PATH
-      /Volumes/CrossToolNGNew/build/output/
