Scratch that.

I assumed that since ‘--with-gnutls’ was already present (and detected
by ./configure, and listed by ldd...), GnuTLS just wasn't enough to
provide the full HTTPS experience and OpenSSL was required. I was
wrong.

The actual solution is a bit silly. All that is actually needed to get
`lynx https://google.com’ working again is:

Yep.

Is this unusual? Can't say I feel much enthusiasm to read/debug
autoconf macros...

My main motivation was to have access to HTTPS sites while working on
my X-less GuixSD box, which works with the patch above. However:

    ~$ lynx https://www.ssllabs.com/ssltest/viewMyClient.html
    Looking up www.ssllabs.com
    Making HTTPS connection to www.ssllabs.com
    Retrying connection without TLS.
    Looking up www.ssllabs.com
    Making HTTPS connection to www.ssllabs.com
    Alert!: Unable to make secure connection to remote host.

Not sure I want to dive into this mess.

Kind regards,
