I use this function.  I takes a list of variables and displays each
one.  As John also said, you can replace "warning" with "info" if you
are using 3.81.  Most of the time, I like to know the line number of
the show-vars invocation when I am debugging my makefiles so I use
"warning".

show-vars = \
$(strip \
  $(foreach .tmp,$(1), \
    $(warning $(.tmp)="$($(.tmp))") \
   ) \
 )

x := 1
y := 2
z := 3

$(call show-vars,x y z)
