For that concern, you could send a feature request to the
GNU ‘make’ mailing list for reporting errors and requesting
features.  See details about that mailing list here:

   https://lists.gnu.org/mailman/listinfo/bug-make

There is also the GNU ‘make’ mailing list for questions
about using that tool:

In this instance, adding the comment after the command is
the more appropriate location (because your comment is
specific to that command and is not a description of the
makefile rule), but you might decide to have all comments
related to a given rule above each rule.

Note that this works when the shell that you have chosen
allows it.  Try:

   M-x shell
   $ echo "My directory is " ${PWD}  #print the current directory

See also (info "(make) Choosing the Shell") if you are
thinking of changing your shell.
