In our build-script (build.rs), we won't set the environment variable 'BUILD_VERSION' when the 'git describe' command failed (e.g. when the current source tree does not contain git information). This patch added a fall back path where the default value of 'BUILD_VERSION' is based on the 'cloud-hypervisor' crate version. Fixes: #1669 Signed-off-by: Bo Chen <chen.bo@intel.com>
