collect2: error: ld returned 1 exit status

Sorry, this didn't work. Looks like libressl has #define OPENSSL_VERSION_NUMBER 0x20000000L (very annoying of them) and proper fix could look like:

diff --git a/libfreerdp/crypto/tls.c b/libfreerdp/crypto/tls.c
index 20fde415d..76f51701f 100644

 	SSL_CTX_set_security_level(tls->ctx, settings->TlsSecLevel);
 #endif

With this patch applied to 2.0.0-rc4 freerdp builds and run (checked with remmina).
