For out-of-tree builds you have to pass the location of your build to our tools like the fuzz script, valgrind script etc. Modify them so that the value can be set in the environment rather than requiring a shell script flag. Set the environment variable in the vagrant provision step, so that the scripts Just Work (TM) in the VM.
