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.
