Description
```
/root/workspace/ceph/build/bin/ceph-authtool --create-keyring --gen-key --name=mon. /root/workspace/ceph/build/keyring --cap mon 'allow *'
creating /root/workspace/ceph/build/keyring
terminate called after throwing an instance of 'std::system_error'
what(): Function not implemented
```
the reason is that we use `check_symbol_exists(getentropy "unistd.h" HAVE_GETENTROPY)` to check whether kernel supports `getentropy` function.
actually in some case, `getentropy` function is declared in unistd.h but not implemented!
