I'm not on ubuntu, but this is what I do (and what garbear has already added to all his readme files too):
I assume your working directory is like: /home/user/devel or sth like that, otherwise the install directory matches your develop directory, then you need to adapt DESTDIR and PREFIX when building the addons.

Code:

git clone https://github.com/garbear/xbmc.git kodi
cd kodi
./bootstrap && ./configure --prefix=/usr && make -j8
make install
make -C tools/depends/target/binary-addons clean
make -C tools/depends/target/binary-addons PREFIX=/usr ADDONS="peripheral.joystick game.libretro game.libretro.nestopia"
