No. $ is a (special?) make variable that contains only a dollar sign. To
expand the variable in the Makefile, you have to write $$ (like for any
other Makefile variable whose name has only a single character, like $@,
$<, etc). As a result, you get a single dollar sign in the shell command
text. :-)
