With this change, you can now cross compile test cases and run them on qemu-user. Here is an example to run our test suits in an emulated ARM32 environment. $ CC=arm-linux-gnueabihf-gcc \ CXX=arm-linux-gnueabihf-g++ \ GCC=arm-linux-gnueabihf-gcc \ GXX=arm-linux-gnueabihf-g++ \ OBJDUMP=arm-linux-gnueabihf-objdump \ MACHINE=arm \ QEMU='qemu-arm -L /usr/arm-linux-gnueabihf' \ make -j16 test
