Instead of setting S to a directory inside the tarball and B to another
directory inside the tarball, use the default value of S and set
AUTOTOOLS_SCRIPT_PATH to the right path to find configure. Update the patches
so they still apply, and clean up the recipe slightly.
Because something is not quite right regarding quilt and patching, add a PR bump
to the recipes to ensure that a clean work directory is used: for some reason
rebuilds will rarely fail to patch correctly.
