Undefined make variable conflicting with environment

[ashar]

The hello demos in both demo/IceBox and demo/IcePack have a target
called $(NAME) in the Makefile, but this variable is not defined
anywhere. I have set NAME as an environment variable with my name as
the value (I think this is because of some other program), so make will
try to make my name as a target, obviously failing. These targets
should either be defined or removed.

Thanks for the bug report, we will fix this!
