#18 Better DISTFILES handling for version modulations

[wahwah]

And excerpt from the maintainers mailing list:

The second thing, version-modulated distfiles. Can we, instead of
creating the list and the filtering it, include only the right
versions? For instance:

DISTFILES_version-$(GARVERSION) = $(GARNAME)-$(GARVERSION).tar.gz

...and then have DISTFILES being assembled by GAR?

I have already tought of something similar as you your left-hand side
would expand during Makefile parsing. You would need some kind of
definition like
VDISTFILES = $$(GARNAME)-$$(VERSION).tar.gz
which would then be expanded during evaluation. It would also allow
automatic upstream watches with substituted $$(VERSION) for
UWATCH and easier version modulations.
