For instance, macOS has the DebugSymbols framework that allows users to specify a local lookup tool to find symbol files given a UUID. That runs only on MacOS and requires MacOS specific headers to build. So that makes it a Host facility. But there's no reason you couldn't use this mechanism for finding Linux symbol files when cross debugging. So that makes it sound more like this Platform symbol finding facility you're envisioning. I'm still a little unclear about the distinction between Host, Platform when the platform isn't the same as the Host, and Platform when it happens to be the same as the Host.

I agree that the host/platform split is not very clear currently.
We'll need to think about it when the time comes. Maybe we just need
to peel off one layer from the Host here and move it somewhere. For
example the concrete details of how to invoke the DebugSymbols
framework can stay in Host (roughly the
LocateMacOSXFilesUsingDebugSymbols function, I guess), but then all
the smartness about what to do with it can live somewhere else.
