failed to run the Lua code for coroutine_api: 4397552097696: coroutine_api:2: attempt to call global 'require' (a nil value)

Compile Openresty for IBM Z/S390x but unable to start due the following issue :

Start by reproducing the failure with the shown resty command and inspect /usr/local/openresty/lualib/resty/core.lua, the nginx.conf locations, and the ngx_lua build arguments from nginx -V. Compare the startup behavior on IBM Z/s390x with the reported OpenResty 1.19.9.1 environment; done means identifying the cause and confirming that both nginx startup and the resty require("resty.core") command work.
