Anas Nashif 2bc9d69981 build: abstract emulation and replace qemu goal with run
This will replace the current goal of 'make qemu' with 'make run' and
moves Qemu handling into its own file and into the boards instead of
being architecture specific.

We should be able to add new boards that support some other type of
emulation (by adding scripts/Makefile.<emu type>) and allow the board to
define their own options for the use type of emulation.

'make qemu' will still work, however it will be deprecated, starting
with this commit it is recommended to use 'make run'.

Hello World
###########

Overview
========
A simple Hello World example that can be used with any supported board and
prints 'Hello World' to the console. This application can be built into modes:

* single thread
* multi threading

Building and Running
====================

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

.. code-block:: console

   $ cd samples/hello_world
   $ make run


To build the single thread version, use the supplied configuration file for
single thread: :file:`prj_single.conf`:

.. code-block:: console

   $ make CONF_FILE=prj_single.conf run

Sample Output
-------------

.. code-block:: console

    Hello World! x86
