Starting in this Maestro bump: dotnet/android#7630

We started seeing:

ILLink error IL1034: Root assembly 'MyAndroidApp, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' does not have entry point.

Might be caused by: dotnet/linker#3124 (comment)

Android apps are class libraries, because there is no static void Main() method.

To work around this I did:

  <Target Name="_FixRootAssembly" AfterTargets="PrepareForILLink">
    <ItemGroup>
      <TrimmerRootAssembly Update="@(TrimmerRootAssembly)" Condition=" '%(RootMode)' == 'EntryPoint' " RootMode="Library" />
    </ItemGroup>
  </Target>

Filing an issue here, to see if this is what we should actually do -- or something else.
