what about the $(shell ..) stuff i used in my example?
of course target-specific variables work like in you example, but 
although not needed,
  t1: TEST:=$(shell find)
would cause find to be executed no matter which make-target i run.
That's the point i want to avoid. I only want the shell-command to be 
run once and only if a specific make-target is run.

TEST=$(shell find) is a workaround in my case, since i use $(TEST) only 
once, but if i would use it multiple times, the shell-command would also 
be executed multiple times. That's again something, that i don't want. 
The shell-command should be executed only once.
