16 - Linux-user emulation
18   We already support Linux user emulation. We can use LoongArch cross-tools to build LoongArch executables on X86 machines,
19   and We can also use qemu-loongarch64 to run LoongArch executables.
21   1. Config cross-tools env.
23      see System emulation.
25   2. Test tests/tcg/multiarch.
27      ./configure  --static  --prefix=/usr  --disable-werror --target-list="loongarch64-linux-user" --enable-debug
29      cd build
31      make && make check-tcg
33   3. Run LoongArch system basic command with loongarch-clfs-system.
35      - Config clfs env.
37        wget https://github.com/loongson/build-tools/releases/download/2022.05.29/loongarch64-clfs-system-5.0.tar.bz2
39        tar -vxf loongarch64-clfs-system-5.0.tar.bz2 -C /opt/clfs
41        cp /opt/clfs/lib64/ld-linux-loongarch-lp64d.so.1  /lib64
43        export LD_LIBRARY_PATH="/opt/clfs/lib64"
45      - Run LoongArch system basic command.
47        ./qemu-loongarch64  /opt/clfs/usr/bin/bash
48        ./qemu-loongarch64  /opt/clfs/usr/bin/ls
