uboot and sunxi-tools now cross compiles on ubuntu 12.04.3:

  # ARM with floating point support cross compiler install
  sudo apt-get install gcc-4.4-arm-linux-gnueabihf
  cd /usr/bin
  sudo ln -s arm-linux-gnueabihf-gcc-4.4 arm-linux-gnueabihf-gcc
  cd ~

  # download and cross compile uboot
  git clone https://github.com/linux-sunxi/u-boot-sunxi.git
  cd u-boot-sunxi
  make CROSS_COMPILE=arm-linux-gnueabihf- EOMA68_A20_FEL
  cd ..
  
  # download and cross compile sunxi-tools
  sudo apt-get install libusb-1.0.0-dev
  git clone https://github.com/linux-sunxi/sunxi-tools.git
  cd sunxi-tools
  make
  cd ..


sunxi-tools gets built with a minor ignorable warning:
