To be honest, I don't think it's worth adding a Config.in choice here.
Just use Gnutls if available, or use OpenSSL if available, and that's
it. I believe it's sufficient, and more in line with how we handle the
other options in ffmpeg (by doing "automatic handling of
optional dependencies")

Best regards;

Thomas
