As I said in my previous mail, I've already tried something like this, but
sadly it kept broking the 'remake-gnulib-add-acsubst.sh' test case, which
exercises a scenario that Gnulib Makefiles need to support.  So no good,
unless we manage to find another idiom that Gnulib can use to have its use
case still working.  Fell free to give it a shot, as I'd be happy to
apply the above simplification.

For the moment, I think we should just apply my patch; we can implement
incremental improvements on it later (if we manage to find them ;-)
