I've installed AFL a few times in the last couple days and have been mildly annoyed by the fact that there is an exit 1 in the qemu build script after each failed dependency. In practice, this means that I (a person who forgot the dependencies) need to run the script several times and install dependencies each time until I have them all. This is a super small patch, but it fixes the issue and just gives you the full list of missing dependencies. I just tested on a fresh Ubuntu 20.04 docker:
root@1c3eaa577e21:/AFL/qemu_mode# ./build_qemu_support.sh

Hopefully this 5 minute fix makes life a little easier for folks :)
