From 01796db0b166e720860eff200acabff410ba6979 Mon Sep 17 00:00:00 2001

Subject: [PATCH 4/7] ssl: enable usage of patched mbed functions conditionally

Only activate support for the MBEDTLS_KEY_EXCHANGE_ECDH_ANON_ENABLED
cipher suite when this is actually available in mbedtls.
This makes it possible to compile IoTivity against a unpatched mbedtls
version.
