GnuTLS does not support reading all files in a directory, but it
supports reading CA certificates in PEM format from a file, see
gnutls_certificate_set_x509_trust_file().  You'll call
gnutls_certificate_verify_peers2() to use it.

IIRC, the file may contain more than one CA certificate, so you should
be able to 'cat /somewhere/openssl/somewhere/* > gnutls-cas.pem' and
use that file, or similar
