uhm, thats a fix for the wrong part of the makefile =)

the for-loop was just a quick hack to overflow the environment-space of 
the SHELL (and maybe to show that make-vars can hold much more memory 
than a processes environment).

In my real-world-makefile, the variable is created by many complex 
calculations, which are not part of a make-target.
In short: I need a replacement for the "@echo $(LARGE_VAR)"-line
