Currently the user is expected to supply the PREFIX on the build.sh
command-line. If the user's environment defines a variable named
PREFIX and the user supplies the PREFIX on the cmdline, which one is
supposed to win? If the environment defines the PREFIX should we
remove the requirement to supply it on the cmdline?
