I believe it's a quite different problem. According to the commit message I did:


"Add support for __REDIRECT_NTH as eglibc makes use of this macro to redirect long double functions to long functions on arch not supporting long double."


So if tcc is ported once to these architecture we'll need it. Also, I don't think it would be convenient for them to do differently. And finally, it's just a small line in tcc. The real stuff is asm aliasing but we probably want to keep this. Or maybe not?
