Qemu

Alternative way to build qemu with Neo 1973 emulation:

# checkout source
svn co https://svn.openmoko.org/trunk/src/host/qemu-neo1973
cd qemu-neo1973

# run configure
./configure --target-list=arm-softmmu --enable-gadgetfs

# needed for gadgetfs to work
ln -s /usr/src/linux/include/linux

# build it
make
