I ran into the no problem when I build eventfd, but my app also throws this error after I updated my zephyr from 3.7.0 to main

[arifbalik]

In my case I was trying to build with 'native_sim' target and CONFIG_SHELL_GETOPT was y selected by CONFIG_NET_L2_WIFI_SHELL. This config is not supported in native_sim anyways, removing it allowed me to n select it
