So no objections from me.

Thanks. Perhaps a better interpretation is that it is unnecessary to make `-fno-pic -mcmodel={tiny,small}` different. The scenarios that uses both `-fno-pic` and C++ exceptions have been increasingly rare now, so there is not many advantage optimizing for the little size saving here.
