I think the intention is to have PACKAGE_VERSION=9.1.0 (and tarball)
for a release (RELEASE=YES in configure.ac).

For development versions PACKAGE_VERSION (and tarball
name) is mangled later in configure.ac after AC_INIT based on current
commit: https://github.com/ghc/ghc/blob/master/aclocal.m4#L1646
