I get the same error, but my build continues and succeeds, so I dont
think this is your problem.

DarwinBuild runs in a chroot, so you really need to look for ./
BuildRoot/usr/bin/xcode-select. That file should be copied into your
buildroot when DarwinBuild first tried to build an xcode project. Do
you have Xcode installed on your host OS? DarwinBuild cannot build
Xcode for you since its not open source.
