Good point. You're right:

in that removing it from automake should not impact any existing
installation of autoconf. However, autoconf's lib/Autom4te hierarchy
is sync'd from automake, so we would still need to make an adjustmake
to autoconf before its next sync.

So fine to remove from automake after all. Good!
