Run autoreconf -vf throughout

I ran

    for i in $(find . -name configure.ac); do pushd $(dirname $i); autoreconf -vf; popd; done

to re-generate all automake/autoconf files throughout the repo (with
upstream autoconf 2.69 and automake 1.15.1).  These were the changes
that came out.  I am pushing this as obvious.
