Build the library correctly:

  * On a Fedora system:

    $ objdump -T /usr/lib64/libcrypto.so.1.1 | grep -w d2i_X509
    000000000020c490 g    DF .text  0000000000000010  OPENSSL_1_1_0 d2i_X509

  * On a FreeBSD system:

    $ nm /usr/local/lib/libcrypto.so.11 | grep -w d2i_X509
    00000000003189a0 T d2i_X509

The list of exported symbols for libcrypto has:

    util/libcrypto.num:d2i_X509   574  1_1_0   EXIST::FUNCTION:

a correct build will result in a libcrypto with this function exported.
