coreclr build failure: "GetTargetMachineInfo" task could not be loaded

[BruceForstall]

With a new, clean runtime clone, src\coreclr\build.cmd fails with:

C:\gh\runtime\tools-local\tasks\installer.tasks\installer.tasks.csproj(42,5): error MSB4062: The "GetTargetMachineInfo" task could not be loaded from the assembly C:\gh\runtime\artifacts\bin\installer.tasks\Debug\netstandard2.0\installer.tasks.dll. Could not load file or assembly 'C:\gh\runtime\artifacts\bin\installer.tasks\Debug\netstandard2.0\installer.tasks.dll'. The system cannot find the path specified. Confirm that the <UsingTask> declaration is correct, that the assembly and all its dependencies are available, and that the task contains a public class that implements Microsoft.Build.Framework.ITask.

I have a PR open that fixes this: #178

[sandreenko]

I have hit this issue, I have the fix from #178. Is git clean required?
