Substitution variables are expanded in versions, but not in commands
such as "merge"; so even if such a variable existed (which it doesn't),
it wouldn't help you.

The only way I know of to achieve this with a single recipe is to figure
out how to merge the multiple packaging branches into one, with
conditional behaviour in debian/rules etc.  This should be possible in
most cases, although I appreciate it isn't always straightforward.
