It's somewhat confusing to declare the target as x86_64- and then the arch as ppc.

Would there be some reason that " -target powerpc-apple-darwin8 " without the -arch and -mmacosx-version-min is not going to work here?
 (after all we are only testing that the driver translates c/l args properly - there is no need to invoke a back end). 

+// CHECK-CHECK-PPC_OSX10_4: "-cc1"
+// CHECK-CHECK-PPC_OSX10_4: -fobjc-runtime=macosx-fragile-10.4
+// CHECK-CHECK-PPC_OSX10_4-NOT: -fobjc-dispatch-method
+// CHECK-CHECK-PPC_OSX10_4: darwin-objc-defaults

+// RUN: %clang -target x86_64-apple-darwin10 -S -### %s \
+// RUN:   -arch ppc -mmacosx-version-min=10.5 2> %t
+// RUN: FileCheck --check-prefix CHECK-CHECK-PPC_OSX10_5 < %t %s
 
likewise " -target powerpc-apple-darwin9 "

+
+// CHECK-CHECK-PPC_OSX10_5: "-cc1"
+// CHECK-CHECK-PPC_OSX10_5: -fobjc-runtime=macosx-fragile-10.5
+// CHECK-CHECK-PPC_OSX10_5-NOT: -fobjc-dispatch-method
+// CHECK-CHECK-PPC_OSX10_5: darwin-objc-defaults
