I just found the reason. It was something like the sequence in the 
appended Makefile. This is a very special case. Try to experiment with 
the foo.mk Makefile, as anything you do will change the output. ;)

En passant I found out that you cannot .undef a variable that has been 
passed via the make(1) environment.

Lots of tricky details ...

.undef UNDEFINED

# this variable references the undefined variable

# here the reference is quoted
VARS+=		${UNDEF_REF:Q}

# and the current value is assigned to another variable

all:
