9c3d3668 - [Build] Don't create a separate target for the object file directory.

[Build] Don't create a separate target for the object file directory. When building Swift sources, don't make a separate target for the object file directory, because it may end up with the same name as would be generated by another invocation of `handle_swift_sources`. Instead, add the command to make the directory to the custom target that actually does the build, which should have a unique name. rdar://115278959
