I was sort of wondering what kind of advantage it would buy us avoiding
linker to decide it for us when the meaning of flag is not definite, but
I guess it would avoid us for requiring to tell linker whether we are
building small or medium model binary.  So I guess I will just follow
PARISC implementation and propose the ABI change here...
