Trying to cross-compile CPython 3.8 using Android NDK toolchain with _socket module enabled. Build fails at:
../Modules/socketmodule.c:6739:5: error: invalid use of undefined type 'struct if_nameindex'
for (i = 0; ni[i].if_index != 0 && i < INT_MAX; i++) {

ni[i].if_index, PyUnicode_DecodeFSDefault, ni[i].if_name);

Without _socket module, the cross-compilation works well. Also the result python3 build transferred to my Android device and tested in Terminal app works well. However without _socket module for example the command:
"python3 -m ensurepip"
obviously fails because of missing _socket module.
