Also fails w/o --subsetCategory CoreCLR...

[jkoritzinsky]

@jkotas this might be related to your changes from ArchType to TargetArchitecture.

[AndyAyersMS]

If you pass --arch x64 it still works.

[jkotas]

Taking a look...

[AndyAyersMS]

w/o --arch the build fails to find SPC for crossgen; I think it ends up in the Linux..Release directory
