You're mixing together a couple types of variables.  $FILES and $file are
shell variables, not Makefile variables, so you need to escape the $ so
that make doesn't expand them and lets the shell expand them.

        (cd $(top_builddir)/$(NSI_INSTALL_DIR)/doc; \
        FILES=`find . -type f`; \       
        for file in $$FILES; do \
            echo "Processing "$$file; \
            todos -p $$file; \
            mv $$file $$file".txt"; \
        done)
