Allow more version number flexibility, by using Automake "gnu" mode.

version number to indicate, for instance, a prerelease and a Git commit
number like 0.8.0-pre1-g12345678.

enable the extra options that "gnits" mode enabled automatically
that we still want to use.

The Automake manual discourages using "gnits" mode anyhow:
