In the marked line:

compile-clean:
        @cd $(lisp) && \
        elcs=`echo "${SUBDIRS_REL} " | sed -e 's|/\./|/|g' -e 's|/\. | |g' -e 's| |/*.elc |g'`; \
        for el in `echo $$elcs | sed -e 's/\.elc/\.el/g'`; do \
          if test -f "$$el" || test ! -f "$${el}c"; then :; else \
            echo rm "$${el}c"; \
            rm "$${el}c"; \
          fi \  <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<
        done

there should be a semi-colon after "fi", I believe.  If you make that
change, does the problem go away for you?
