anyway, this file should be here, as it is added into Makefile:


===========
git clone git://git.kernel.org/pub/scm/virt/kvm/mst/qemu.git tmp
cd tmp/
git checkout for_upstream
./configure  --target-list=x86_64-softmmu
make -j9
 > make: *** No rule to make target `stubs/pc_dimm.o', needed by 
`libqemustub.a'.  Stop
