lang/node and libressl

[Giovanni Bechis]

While trying to make lang/node build with libressl I found that some macros 
needed are not present in libressl.
Some of them has been added by this commit in openssl 
(https://github.com/openssl/openssl/commit/7b6b246fd393cbe07bc1f0d456140efdff59f971)
 like SSL_CTX_get0_chain_certs; should I patch lang/node or would it be better 
to cook a diff for libressl instead ?
 Cheers
