Could it be that Bernd thinks your shell variable assignments, intended
for command lines of a target where the shell will handle the backticks,
are make variable assignments?

    $ cat makefile
    #! /usr/bin/make -f

    BAR = 3.14

    foo::
            xyzzy="$$USER $(BAR)" && \
            echo $(BAR) `expr 6 \* 7` $$TERM $$xyzzy
    $
    $ ./makefile
    xyzzy="$USER 3.14" && \
            echo 3.14 `expr 6 \* 7` $TERM $xyzzy
    3.14 42 xterm ralph 3.14
    $

Cheers, Ralph.
