I cannot reproduce your results on current master branch:
SHA1:d22c8be964a870f59d2fdab6c67cefa0c4799364
for this series applied.
echo $SOURCE_DATE_EPOCH
1567523778
./tools/buildman/buildman.py -b HEAD --count=3 ls1043
--output-dir=../BUILD/ --force-build -CveE
./tools/buildman/buildman.py -b HEAD --count=3 ls1043
--output-dir=../BUILD/ -Ssdel
Just gives me some warnings (without the size difference):

Am I doing something wrong? Or am I missing any extra switches for
buildman?
And I don't know why the ' -b HEAD..HEAD~~~ ' option returns:
Range 'HEAD..HEAD~~~' has no commits , as I'm able to use HEAD with
-b switch and count=X ?
