Closed Issue: Build Error: EF.skipstrongnames.targets(17, 5) Null Reference [933]

I downloaded master from git and ran the ```build /t:RestorePackages``` command. Then, I ran ```build```. It failed with the error

> C:\\...\entityframework\tools\EF.skipstrongnames.targets(17,5): error: Oject reference not set to an instance of an object.

I have included the output of the process.

I assume this has to do with BriceLambson's work on integrating the strong name skipping into the main build process. Just thought Brice might want to see something from the wild.
