Brian's "he is too lazy to commit this so Eric is going to have to do it" environmental variable hack for prefix. This allows you to just set a prefix in your profile which will be used in all of your builds. AKA you can be even lazier(!) about calling BUILD scripts. Don't blame Eric, Brian borrowed his keyboard.


BUILD/SETUP.sh:
  Added option to set environmental variable in case you are lazy about setting prefix (ala Brian)
BUILD/autorun.sh:
  Change of syntax
