Nir / Didi, it seems related to the gitignore patch you did in the make script:
[2019-12-08T05:22:45.783Z] git ls-files | tar --files-from /proc/self/fd/0 -czf "ovirt-engine-4.4.0_master.tar.gz" ovirt-engine.spec
[2019-12-08T05:22:45.783Z] tar: .gitignore: Cannot stat: No such file or directory
[2019-12-08T05:22:54.107Z] tar: Exiting with failure status due to previous errors
[2019-12-08T05:22:54.107Z] make: *** [Makefile:361: dist] Error 2
