In principle, if you set CPU_TARGET before calling ./build_qemu_support.sh, you should get a build capable of running non-native binaries (say, you can try CPU_TARGET=arm). This is also necessary for running 32-bit binaries -on a 64-bit system (CPU_TARGET=i386). +on a 64-bit system (CPU_TARGET=i386).
