configure: test that makeinfo supports the @sortas command
* acinclude.m4 (OCTAVE_PROG_MAKEINFO): Test that makeinfo supports the @sortas
command, print a warning and disable docs if it doesn't. This makes explicit
the newest command required to build the manual, which depends on Texinfo 6.1
and newer.
* configure.ac: Update disabling documentation warning messages.
