We have a strong check for GCC >= 4.8, but don't validate any version number for CLang historically. This defines the min CLang to be 3.4 which is what is available for RHEL-7. macOS uses a different versioning scheme for CLang, based off XCode versions. There is a mapping recorded at https://en.wikipedia.org/wiki/Xcode#Toolchain_versions Here we see upstream CLang 3.4 corresponds to XCode 5.1 XCode 5.1 is available for macOS 10.8.4 or later which trivially satisfies our platform support matrix requirements. All these versions match what QEMU declares for its min GCC and CLang checks. Reviewed-by: Fabiano Fidêncio <fidencio@redhat.com> Signed-off-by: Daniel P. Berrangé <berrange@redhat.com>
