I would recommend to stay on the conservative side and only add ones
that we're sure we need for specific ebuilds. We can remove flags later,
but it's better if can avoid adding unneeded ones in the first place.

I think it's pretty clear that the 'prefix' flag is special, so I would
go ahead and add it.
