That's not true.  All sh-style shells parse entire commands before
attempting to execute them.

Add a dummy argument before or after the $(tmac-wrap) in the for command,
or do something like 

      if test -n "$(tmac-wrap)"; then \
	  TMAC_WRAP="$(tmac-wrap)" ; \
          for m in $$TMAC_WRAP; do \
              ...
          done; \
      fi
