/usr/bin/ld: ./.libs/libsss_sbus.so: undefined reference to `sss_chain_id_set'
```
This is because `sss_chain_id_set` is covered by `#ifdef BUILD_CHAIN_ID` and this mock
build does not detect patched version of tevent: `configure: Chain id support is disabled
due to missing dependencies in tevent`
This way `sss_chain_id_set` call is undefined.
