savedefconfig can be tricky because of risk of loosing options:
1. it will remove options which became the default or became selected,
2. later when the default is changed or selecting option is removed, the
first option from #1 will not be brought back.
This was already for example with DEBUG_FS and the conclusion that time
was - do not run savedefconfig automatically.
Therefore if some symbol(s) can be safely removed, patch is welcomed.
