[Build-common-hackers] Bug#359887: cdbs: Flag minimal CDBS version

[Ian Wienand]

Package: cdbs
Version: 0.4.37
Followup-For: Bug #359887

Hi,

OK, I can see that back-porting might be unsuitable.

I also see that generating control.in from rules in a bad idea, but I
really like my Makefiles that build packages being able to
automagically fill in dependencies that CDBS needs.

How about something like the follow, where you allow a flag for a
minimal version?

Thanks,
