You can also build statically linked versions of the afl++ binaries by passing the STATIC=1 argument to make:
```shell
$ make all STATIC=1
```

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). If you're trying to run QEMU on a
different architecture you can also set HOST to the cross-compiler prefix
to use (for example HOST=arm-linux-gnueabi to use arm-linux-gnueabi-gcc).
You can also compile statically-linked binaries by setting STATIC=1. This
can be useful when compiling QEMU on a different system than the one you're
planning to run the fuzzer on and is most often used with the HOST variable.
Note: if you want the QEMU helper to be installed on your system for all
users, you need to build it before issuing 'make install' in the parent
