That won't happen and is impossible -- while I don't have an example, in
general you can't build an old version of, say, coreutils with today's
gnulib, or expect that a future version of coreutils will work with
today's gnulib.  I'm sure trying old enough coreutils, or some other
project that use gnulib, will come up with an example that breaks the
build (or produce incorrect results).
