[swift-dev] build-script has newfound interest in ninja source?

[David Zarzycki]

So after updating my sources, build-script fails to work with the following error:

./utils/build-script: fatal error: can't find source directory for ninja (tried /Volumes/data/wt/swift/master/ninja)

Why does it care about where my ninja source is? Why does "--build-ninja false" not work?

Thanks,
Dave
