Fails to build using lld

[mssun]

I followed the using lld section in the README but failed with some error.

Thanks for the heads up. This is due to a breaking change in the target specification from a recent nightly change. #157 should fix this.

This particular error was fixed in #157 so I'm going to close this issue. Let me know if you run into any other problem!
