Like so:

        @libname=`sed -ne "/^library_names=/{s/.*='//;s/'$$//;s/ .*//;p;}" \
                  $(DESTDIR)$(toolexeclibdir)/libstdc++.la`; \
        libname='' ; \
        if [ -z "$$libname" ]; then \
          libname=`sed -ne "/^old_library=/{s/.*='//;s/'$$//;s/ .*//;p;}" \
                  $(DESTDIR)$(toolexeclibdir)/libstdc++.la`; \
        fi; \
        echo " $(INSTALL_DATA) gdb.py
$(DESTDIR)$(toolexeclibdir)/$$libname-gdb.py"; \
        $(INSTALL_DATA) gdb.py $(DESTDIR)$(toolexeclibdir)/$$libname-gdb.py
