using another build tool

[PhilipDeegan]

the nginx build generates this on the fly and inserts it into the .so

might be useful to have it as an optional thing, or mention

extern ngx_module_t  ngx_http_hello_world_module;

ngx_module_t *ngx_modules[] = {
    &ngx_http_hello_world_module,
    NULL
};

char *ngx_module_names[] = {
    "ngx_http_hello_world_module",
    NULL
};

char *ngx_module_order[] = {
    NULL
};
