./configure: error: unsupported LuaJIT build; ngx_stream_lua_module requires LuaJIT with FFI enabled.
ERROR: failed to run command: sh ./configure --prefix=/usr/local/openresty/nginx ...

Reproduce the reported commands and inspect ./configure and auto/feature around the LuaJIT FFI check, especially the shell command shown failing. Trace the generated quoting and rerun the configure step with the reported LUAJIT_LIB and LUAJIT_INC values; done means the check completes without the unexpected EOF or unsupported LuaJIT build error.
