Oops, I got it wrong, the install would not be reexecuted the second time.

Maybe someting more like:
  ifdef USE_ONE_INSTALL  TMP_INSTALL = .tmp_install.once  else  TMP_INSTALL = .tmp_install.$(MAKE_NONCE)  endif
  $(TMP_INSTALL):      $(RM) -r ./tmp_install .tmp_install.*      # do installation...      touch $@

So that the file target is different each time it is run. Hopefully.
