This isn't a bug. Your machine is just missing a gnutls installation.
You can run configure and pass --with-gnutls=ifavailable to compile
Emacs without gnutls support, or you can install gnutls on your machine
(for example, gnutls installed with Homebrew will automatically get
picked up by the Emacs configure script).
