  Log:
    ext/openssl/extconf.rb: do not use -Werror=deprecated-declarations
    
    It fails to build on Solaris:
    
    ```
    ossl_cipher.c: 関数 ‘ossl_cipher_init’ 内:
    ossl_cipher.c:228:2: エラー: ‘EVP_md5’ is deprecated [-Werror=deprecated-declarations]
      228 |  EVP_BytesToKey(EVP_CIPHER_CTX_cipher(ctx), EVP_md5(), iv,
          |  ^~~~~~~~~~~~~~

    ```
    
    I agree that `-Werror=` is a good habit, but adding it by default is too
    aggressive.
