description:
Sprinkle OPENSSL_NO_EC_NISTP_64_GCC_128 for aarch64eb.

Otherwise, the following tests fail with wrong results:

- crypto/libcrypto/t_ciphers:evp
- crypto/libcrypto/t_pubkey:ec

Official document says ec_nistp_64_gcc_128 does not support big endian:
https://github.com/openssl/openssl/blob/master/INSTALL.md#enable-ec_nistp_64_gcc_128
Thanks @a_rin for pointing this out on Twitter!

Note that an equivalent hack was present in openssl.old for aarch64eb,
alpha, and sparc64. But:

- alpha received upstream fix (PR lib/55701)
- sparc64 has been fixed differently (PR port-sparc64/57472)
