There are many more packages to fix, this is just a start.
Rules:
* Don't repeat the package name (not always that easy...)
* Start with capital letter
* Don't end with full stop
* Don't start with "The ..." or "A ..."
I've also added descriptions to some packages and rewritten others.
There is a test that fails on mips, and that breaks the nix build.
The text does not exist anymore in automake upstream git, so the next
version may not need this mips-specific disabling.
