description:
Add a linker map to hide all the symbols the this library accidentally
exported. In particular the following symbols:

DSA_SIG_free
DSA_SIG_new
DSA_do_sign
DSA_do_verify
DSA_free
DSA_new
DSA_size
RSA_check_key
RSA_free
RSA_generate_key
RSA_new
RSA_private_decrypt
RSA_private_encrypt
RSA_public_decrypt
RSA_public_encrypt

conflict with libcrypto and break pkg_add which links against both
libraries.
