The supported configure options include all of the standard TEA configure script
options, plus:

  --disable-tls1          disable TLS1 protocol
  --disable-tls1_1        disable TLS1.1 protocol
  --disable-tls1_2        disable TLS1.2 protocol
  --disable-tls1_3        disable TLS1.3 protocol
  --enable-debug          enable debugging mode and output more status
  --enable-ssl-fastpath   enable using the underlying file descriptor for talking directly to the SSL library
  --enable-hardening      enable hardening attempts
  --enable-static-ssl     enable static linking to the SSL library

If either TCL or OpenSSL are installed in non-standard locations, the following
configure options are available. For all options, see ./configure --help.
