[api-compatibility] Use d15-4 API definitions

jonpryor · jonpryor · commit bb02dffd1deb · 2017-08-25T09:59:29.000-04:00
The [most recent xamarin-android/master build is not green][xa564], because of a failure in the `api-compatibility` tests: [xa564]: https://jenkins.mono-project.com/view/Xamarin.Android/job/xamarin-android/564/ ABI BREAK IN: mscorlib.dll  <div> <h2>Namespace System.Collections.Generic</h2> <h3>Removed Type <span class='breaking' data-is-breaking>System.Collections.Generic.CollectionExtensions</span></h3> </div>  The cause for the breakage is that [xamarin-andorid-api-compatibility was updated for mono/2017-06][0], and `mscorlib.dll` is incompatible between mono/2017-04 and mono/2017-06. [0]: xamarin/xamarin-android-api-compatibility@ed8d914 Since Xamarin.Android d15-4 and current master are both using mono/2017-04, the result is the above "ABI BREAK" message... *all the time*. Update xamarin-android/master to use [xamarin-android-api-compatibility/d15-4][1], fixing the ABI BREAK build error.
