Using the latest master with the patch for OpenSSL 1.1, qca fails to build with OpenSSL 1.0.1f.

According to the OpenSSL doc:
"X509_get0_signature() and X509_get_signature_nid() were first added to OpenSSL 1.0.2."
https://www.openssl.org/docs/man1.1.0/crypto/X509_get_signature_nid.html

Is OpenSSL 1.0.1 not supported anymore?

Thanks.
