Few test case failures on rhel 7.6 ppc64le

[SantoshMagdum]

Hi All,

I had build the nginx binary on rhel 7.6 ppc64le (version 1.17.1.1rc0) from source code - https://github.com/openresty/openresty.
Please note that, I had copied and used ppc64le compiled LuaJIT code while building openresty (nginx).

Below command I used to compile the openresty -

./configure --with-cc-opt="-DNGX_LUA_USE_ASSERT -DNGX_LUA_ABORT_AT_PANIC" --with-http_image_filter_module --with-http_dav_module  --with-http_auth_request_module --with-poll_module --with-stream --with-stream_ssl_module --with-stream_ssl_preread_module --with-http_ssl_module --with-http_iconv_module  --with-http_drizzle_module --with-http_postgres_module --with-http_addition_module --add-module=/usr/openresty/openresty_test_modules/nginx-eval-module --add-module=/usr/openresty/openresty_test_modules/replace-filter-nginx-module

And then tried to execute the test cases for 'lua-resty-memcached' like below -

# pwd
/usr/openresty/openresty/openresty-1.17.1.1rc0/build/lua-resty-memcached-0.14
# prove -r t/

NOTE: The 'lua-resty-memcached' version downloaded from openresty bundle is 0.14

And I am getting below kind of errors -

# prove -r t/

Please help suggest if I need to export any specific environment or should try any compiler flag/somehow increase the timeout value to make these test cases pass.
