I think it is probably a bug that "git non_existent_command"
returns its error message to stdout without an error, where
"git-non_existent_command" behaves differently and does return an
error.
Older versions of git did not implement "git describe" and
GIT-VERSION-GEN produces an empty version string if run on
a system with such a git installed. The consequence
is that "make rpm" fails.
This patch fixes GIT-VERSION-GEN so that it works in the
absence of a working "git describe"

Note: with this commit, the GIT maintainer workflow must change.
GIT-VERSION-GEN is now the file to munge when the default
version needs to be changed, not Makefile. The tag needs to be
pushed into the repository to build the official tarball and
binary package beforehand.
