'The referenced component could not be found' spurious warning on Windows builds using nugets that contain native references

[chamons]

Builds on Visual Studio for Windows using libraries with native references may produce the following warning:

'The referenced component 'PATH' could not be found.'

This is a false warning, the component was successfully linked (unless you have a mtouch warning\error later).

This is due to the unfortunate choice of "NativeReference" in project files for Xamarin dependencies, which clashes with an existing Windows target.

It would be rather difficult to fix this in an backwards compatible way.

Steps to Reproduce

1. Create a new iOS project on Windows
2. Add a reference to a nuget that contains a native reference .a file, such as https://www.nuget.org/packages/Microsoft.CognitiveServices.Speech
3. Build

Expected Behavior

No warnings

Actual Behavior

Not a build warning in the log, but you will get a warning in the IDE of 'The referenced component 'PATH' could not be found.'

Environment

Latest stable
