+ MBEDTLS_DEBUG_C
+
+For targets with space constraints, one might want to compile mbed TLS
+without MBEDTLS_DEBUG_C defined, to save some tens of kilobytes.  Make
+sure OpenVPN still compiles if that is the case.

-openvpn: remove call to PolarSSL debug function
-
-OpenVPN >=2.3.11 uses PolarSSL debug functions for improved logging.
-This requires that PolarSSL is built with POLARSSL_DEBUG_C, which increases
-its size significantly.
-
-This change does not impact OpenVPN operation, see:

-Subject: [PATCH] Fix polarssl / mbedtls builds
-
-Commit 8a399cd3 hardened the OpenSSL default cipher list,
-but also introduced a change in shared code that causes
-polarssl / mbedtls builds to break when no --tls-cipher is
-specified.
-
-This fix is backported code from the master branch.
