This doesn't actually build

tests/pkix_asn1_tab.c:9:6: error: "LIBGNUTLS_VERSION_NUMBER" is not defined [-Werror=undef]
     (LIBGNUTLS_VERSION_NUMBER >= 0x020600)
      ^~~~~~~~~~~~~~~~~~~~~~~~
cc1: all warnings being treated as errors

This is because you missed the gnutls.h include. Rather than
repeating the condition here, you sould just #include the
existing tests/crypto-tls-x509-helpers.h header
