Issue Description:
People have tried to use Swift in Xcode Run Script build phases, but because Swift looks at the SDKROOT environment variable, the Run Script phase will fail when building a non-macOS target:
<unknown>:0: warning: using sysroot for 'iPhoneOS' but targeting 'MacOSX'
<unknown>:0: error: unable to load standard library for target 'x86_64-apple-macosx10.14'
We should just ignore SDKROOT when running the interpreter. Swift knows how to invoke xcrun to find the right SDK when it's not passed one explicitly.
