These undefined symbols should not be a problem. `sys_mbox_trypost_fromisr` doesn't seem to be used, otherwise your application would crash on the first time when the function is called.

When I was investigating this undefined symbols problem a year ago, I was already wondering why the linker is complaining about them even though they are not required. At that time I figured out that these symbols are not in the binary on other platforms. On other platform also function `tcpip_callbackmsg_trycallback_fromisr` which is calling `sys_mbox_trypost_fromisr` isn't in the binary. But, on ESP32 it is. I will try to add `-ffunction-sections` compiler options so that not used function can be optimized out.
