Building Phometheus from source results in new binary checksum every time

Hi! Due to strict security rules we are forced to build Prometheus from scratch, then our security team build it from scratch once more and checksums should be equal. But every time we build Prometheus from source we get a new checksum for resulting binary. Is there any timestamp, uuid, or key added to binary on make? Is there any way to force make to produce same binary on every build?
Thank you in advance.
