Build Bootloader
The Bootloader is also preinstalled on the AVR. There should be no reason to change the bootloader. Nevertheless, if you have to do so, all required sources and commands are in the git repos. You will need a compatbile ISP programmer (for example usbasp) to upload the bootloader image to the AVR. Please be careful with the fuse settings and don't mess around, otherwise you can render your MCPU useless and have to replace the chip yourself. Checkout and compile the bootloader like this:
git clone git://github.com/optixx/quickdev16.git
cd quickdev/avr/bootloader
make all
Flash Bootloader
Connect your ISP programmer to the Quickdev16 and flash the bootloader like this:
avrdude -u -p m644 -c usbasp -U flash:w:bootloader.hex
