Does “we don’t support big-endian anyway” include tools such as `widl`? That’s where this stuff gets used on BE systems (see for example the SHA1 algorithm in https://gitlab.winehq.org/wine/wine/-/blob/3db7506221e44e8091887d7eb42fe1666...) — or perhaps more accurately, gets built, I’m not sure anyone actually uses `widl` on a BE system.
