configure: add a tips for installing libubsan

Browse Source 
In practice, libubsan has been installed but there will still be such alarms sometimes.
In fact, this has something to do with the GCC version.
Most users may not think of it immediately, so they will be confused and waste time here.
So I think we should add a hint here.
