Makefile,genbuild: Provide length for abbreviated commit hashes
The original default, minimum abbreviated hash length was 7. It dif-
fers on newer systems, however. This breaks reproducibility, so set
an explicit length. 12 hex digits should be good enough.
Note: This sets only a minimum. With a high enough number of commit
objects in the repository, Git could still decide to use a longer
hash, again breaking reproducibility. 12 digits will hopefully pro-
vide enough margin.
