Thanks! When you manually patch your machine with this file, does it successfully build corefx for you in your path with spaces?

[Tyrrrz]

Yeah it does. Basically that's how I've debugged it and found these issues.

Thank you for your contribution. As announced in dotnet/coreclr#27549 this repository will be moving to dotnet/runtime on November 13. If you would like to continue working on this PR after this date, the easiest way to move the change to dotnet/runtime is:

1. In your coreclr repository clone, create patch by running git format-patch origin
2. In your runtime repository clone, apply the patch by running git apply --directory src/coreclr <path to the patch created in step 1>

@maryamariyan is there a chance it will get merged before then? :)
