Based on https://github.com/esden/summon-arm-toolchain

I have made the following changes:

• Set the default flags so that everything builds on my system
• Updated Linaro GCC to version 4.8-2013.07-1
• Updated Linaro GDB to version 7.6-2013.05
• Updated newlib to version 2.0.0
• Build the master branch of openocd (for STM32F4 support)
• Added st-link support to the openocd build flags
• Added support for tar.xz archive files
• Removed unused code and patches
• Adapted the gcc-t-arm patch for gcc 4.8
• And a few other small changes

Usage on debian-based linux distributions (e.g. Ubuntu):

1. Install dependencies sudo apt-get install build-essential git flex bison libgmp3-dev libmpfr-dev libncurses5-dev libmpc-dev autoconf texinfo libtool libftdi-dev libusb-1.0-0-dev zlib1g zlib1g-dev python-yaml

2. Run the script ./summon-arm-toolchain

3. (Optional) add to path sudo su echo 'export PATH=/home/YOUR_USER/sat/bin:$PATH' > /etc/profile.d/arm_tools.sh exit

4. Done!
