Make: Make "make dist" catch stale configure

As commit 1ec9b94 explains, the version reported by configure is fixed
at configure generation time.  "make dist" happily distributes a stale
one.  Not terrible, because all that's stale is the output of
configure --version, just embarrassing.

Make gen-tarball-version fail when the configure --version doesn't
match the tarball version.
