git-version-gen: revert "detect untagged revisions" Revert commit bedd7833 as it breaks `make dist` in Inetutils at least, due to the interdependencies with top/GNUMakefile, which depend on the tag prefixes. This results in `make dist` inducing a new call to autoconf where a simple tar-ball build would be expected.
