When you're using USE_DOCKER, USE_LXC or USE_VBOX, if you specify mutliple variables you're going slowly to some undefined behavior.
Also, if you set a variable with the value 0, USE_LXC = 0 the software will see it as using LXC because it's checking if the variable is set whatever the value is.
Suggestion
I added some value check when those variables are used, mainly checking if the value is equal 1. This allow users to specify USE_* with the value 0 or 1 and to set multiple variables at once with less conflict.
But still some undefined behavior, like what happen if multiple variables are set to 1.
