long double functions stubs

Are there stubs of functions that operate with long double types like `roundl()`, `sinl()` and so on? I can not find it. I found such stubs in glibc and newlib, hence I wonder shouldn't OpenLibm provide these stubs for the platforms which have `long double` equal to `double` type if the check below failed?
