When I did some experiments with this I found the same:
-8<---------------------------
TEST += world
all:
echo $(TEST)
-8<---------------------------
$ make
echo world
world
$ make TEST=hello
echo hello
hello
$ make TEST+=hello
echo hello
hello
So I had to use an extra variable:
-8<---------------------------
TEST2 += $(TEST) world
all:
echo $(TEST2)
-8<---------------------------
$ make
echo world
world
$ make TEST=hello
echo hello world
hello world
