Support #599

This is a guide on how I compiled an image of Yocto Linux for the Intel Galileo SoC on Arch Linux.
*WARNING*: Arch Linux is not an officially supported build OS for Yocto Linux.
h2. Prepare the Environment
* Edit the pacman configuration:
<pre>
sudo nano /etc/pacman.conf
</pre>
#* And enable the multilib repository:
<pre>
[multilib]
Include = /etc/pacman.d/mirrorlist
</pre>
* Refresh the pacman repo cache:
<pre>
sudo pacman -Sy
</pre>
* Install a few prerequisite packages:
<pre>
sudo pacman -S git python2 cpio gawk wget diffstat unzip gcc-multilib texinfo chrpath socat sdl xterm
</pre>
* Install bitbake from the AUR:
<pre>
yaourt bitbake
</pre>
h3. Fix Python environment
* Create a dummy bin folder in the user directory:
<pre>
mkdir ~/bin
</pre>
#* Then add a symlink python to python2 and the config scripts in it:
<pre>
ln -s /usr/bin/python2 ~/bin/python
ln -s /usr/bin/python2-config ~/bin/python-config
export PATH=~/bin:$PATH
</pre>
* Finally put the new folder at the beginning of your PATH variable:
<pre>
echo 'export PATH=~/bin:$PATH' >> ~/.bashrc
</pre>
h2. Download the Source Code
* Create a directory for the source code:
<pre>
mkdir ~/git && cd ~/git
</pre>
* Get the latest IoT Yocto Development Kit:
<pre>
git clone -b devkit-daisy git://git.yoctoproject.org/meta-intel-iot-devkit iotdk
cd iotdk
</pre>
* Source the @iot-devkit-init-build-env@ script:
<pre>
source iot-devkit-init-build-env
</pre>
h2. Build the Yocto Image
* Run bitbake to build iot-devkit-image:
<pre>
../bitbake/bin/bitbake bitbake iot-devkit-image
</pre>
#* *NOTE*: There are many types of image targets for bitbake to use, such as:
*# *iot-devkit-image*: A fully functional image to be placed on an SD card
*# *iot-devkit-prof-dev-image*: A fully functional image to be placed on an SD card with full profiling and dev tools
*# *iot-devkit-prof-image*: A fully functional image to be placed on an SD card with full profiling
*# *iot-devkit-spi-image*: A small image capable of fitting into the on-board SPI flash
* Fix the grub bitbake source:
<pre>
nano ~/git/iotdk/meta-quark-bsp/recipes-bsp/grub/grub_0.97.bb
</pre>
#* And the SRC_URI to the following:
<pre>
SRC_URI = "git://github.com/intel-iot-devkit/grub-fedora.git"
</pre>
* (Optional) To use the Hob GUI to assist in building, run:
<pre>
bitbake -u hob
</pre>
