Subject: [PATCH] Fix -print-target-triple OS version for apple targets
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.
