bug#48214: inetutils-1.9.4 build fails

[Bone Baboon via Bug reports for GNU Guix <bug-guix@gnu.org>]

I have done several pulls since reporting that inetutils failed to
build.  I can now build inetutils-1.9.4 successfully.  I still have IPv6
disabled. I do not know what the cause of the build failure was.  I do
not know why it can now build (likely a recent commit).
