bug#66537: configure: error: The Guile bindings of GnuTLS are missing

[Hiep Pham]

Hi,

I'm on Fedora and started a shell with:

```
guix shell -D guix help2man git strace --pure
```

And then:

```
./bootstrap
./configure --localstatedir=/var
```

And it showed me this error:

```
[snip]
checking for guile-3.0 >= 3.0.3... yes
checking for guile-3.0... yes
checking if (gnutls) is available... no
configure: error: The Guile bindings of GnuTLS are missing; please 
install them.
```

I started the shell again with some dependencies but no luck :(

```
guix shell -D guix git strace guile-gnutls gnutls --pure
```

My current (guix describe):

```
   guix 8e8d20b
     repository URL: https://git.savannah.gnu.org/git/guix.git
     branch: master
     commit: 8e8d20b6b35d3ab529f9045cc8a779cdcec9c471
```
