Change Platform::GetRemoteSharedModule so if it's given a ModuleSpec which specifies a file path and UUID but not an architecture, open the file at that path and try every one of the architectures in the file to see if there is a UUID match.  Currently we'll pick the first slice of a multi-architecture file and return that as the match, and when the UUID doesn't match because it's the wrong architecture, we'll end up ignoring the file.
