Issue Description:

When compiling with "buildbot_incremental,tools=RA,stdlib=RA,xcode", swiftpm, llbuild both build in Xcode debug mode even though release is specified.

I worked around this by disabling the building of llbuild/swiftpm with that preset.

I'm not sure build-script's notion of "release" or "debug" is forwarded on to any subprojects other than Swift or LLVM.

This should be fixed for swiftpm by swiftlang/swift#6432
