<!--LLVM PR SUMMARY COMMENT--> @llvm/pr-subscribers-clang Author: Gábor Horváth (Xazax-hun) <details> <summary>Changes</summary> The target needs to be initialized in order to computer the correct target triple from the command line. Without initialized targets the OS component of the tripple might not reflect what would be computer by the driver for an actual compiler invocation.
