guix-kreyren/configure.ac
Ludovic Courtès 1dbe3a8db0
build: GnuTLS is now a hard dependency.
Discussed as part of <https://bugs.gnu.org/25975>.

* configure.ac: Check for (gnutls) and error out if it's missing.
* doc/guix.texi (Requirements): Move GnuTLS from optional to required.
(Substitutes): Remove footnote about the need for GnuTLS.
