clang regression Driver/android-ndk-standalone.cpp

Hi,

clang regression Driver/android-ndk-standalone.cpp is run when I running in a x86 machine. Because it check for

// CHECK-I686: “-internal-isystem” “{{.*}}/include/c++/4.9”

thus it failed when my gcc is not 4.9.

Maybe we should disable this case in x86?

Thanks
