Fix build with recent ASIO and automake (#1817658)
    
    Since automake is now newer than the version used to produce the
    tarball, our patch that touches gi-overrides/Makefile.am causes
    the build to fail - we need to run aclocal and automake to fix
    this. To fix the ASIO-related build failure reported as #1817658
    we have to build with `-DASIO_ENABLE_BOOST` - asio now uses
    standalone mode automatically when C++11 or later is detected,
    but it seems abiword can't build this way. See
    https://github.com/chriskohlhoff/asio/commit/265e75cd and
    https://github.com/openscenegraph/OpenSceneGraph/issues/921 for
    more on that.
