We can always try, but I don't think it likely that the autoconf
maintainers will take back the changes because it changes the expected
behaviour of autoconf to such a large degree. The change is also
quite hackish, and until I or another person learns more about
autoconf innards, it's likely to stay that way.

Yes, but I think we can just leave those packages alone instead of
trying to convert them to using pkgautoconf. I was envisioning that
we commit the pkgautoconf stuff, then just go through the packages
one-by-one to convert them as the need arises. Not all packages that
use GNU configure need to be run through pkgautoconf, so that
simplifies things for us initially.

Well, even the build-time dependency can be onerous for some (see
pkg/13004), and I imagine that we should try to slim things down for
platforms where disk space is tight, though I don't think it should be
our number 1 priority during the initial phase of the conversion to
