Yauheni Kaliuta 22a2a392d3 BUILD: Fix Version Define Being Added to All Code Objects
Due to a quirk of target specific make variables which means they
are added to all pre-requisities, this resulted in the defines which
were meant to be applied only to the version module being applied to
most of the codebase.

This did not cause any direct issues, but was untidy and unexpected
behaviour which was reported in Pull Request 1946 by janisozaur.

Fix it by defining a special rule for version.o with own flags
instead of using template rule.
