Introduced by commit fac97c65c distributing cfg.mk, which
previously could blindly assume it was in a git checkout.
* cfg.mk (_update_required): Also check for .git.
* autogen.sh: Don't run bootstrap from a tarball.

This should fix the issues of mistakenly running git on a tarball,
as reported here:

It does. ACK.
