openssl: Use linux-latomic target for ARC

Browse Source 
Some atomic ops for 32-bit ARC processors are implemented in GCC's libatomic.
For example those dealing with 64-bit data (e.g. __atomic_load_8()) as well as
some others. That said it's required to add "-latomic" for successful linkage.

Otherwise error messages like this happen on OpenSSL building for ARC:
------------------------------->8------------------------------
| ...ld: libcrypto.a(libcrypto-lib-threads_pthread.o): in function `CRYPTO_atomic_or':
| .../openssl-3.0.0/crypto/threads_pthread.c:219: undefined reference to `__atomic_is_lock_free'
| ...ld: .../openssl-3.0.0/crypto/threads_pthread.c:219: undefined reference to `__atomic_is_lock_free'
| ...ld: .../openssl-3.0.0/crypto/threads_pthread.c:220: undefined reference to `__atomic_fetch_or_8'
------------------------------->8------------------------------

Fix that by using a special target, which does exactly what's needed.
See [1] and [2] for more details on the matter.
