Thank you very much, Goswin.

the required libs may conflict with the target file. Now I build a
static qemu-arm.

Host> cd qemu-0.12.3
Host> ./configure --target-list=arm-linux-user --static
Host> make
Host> sudo cp arm-linux-user/qemu-arm /target/bin/qemu-arm
Host> sudo cd /target
Host> sudo chroot . /bin/qemu-arm /bin/sh
Host> /bin/qemu-arm /bin/ls

Now, it can work.
Regarding to binfmt-misc, I don't know it.

Well, it's not a good idea.
