This might fix the new CI build failure:

    Makefile.am:4:   The usual way to define 'LIBTOOL' is to add 'LT_INIT'
    Makefile.am:4:   to 'configure.ac' and run 'aclocal' and 'autoconf' again.
    Makefile.am:4:   If 'LT_INIT' is in 'configure.ac', make sure
    Makefile.am:4:   its definition is in aclocal's search path.
