Ticket #3029: configure.ac: warning about unknown '--with-' / '--enable-' options.

Browse Source 
As we use 'AC_CONFIG_SUBDIRS' macro for samba sources option checking is
disabled for us.

Before the patch:

    $ ./configure --with-i-have-misspelled-editor-for-edit
    ...
    # no warnings

The patch enables warnings back only for top-level ./configure:

    $ ./configure --with-i-have-misspelled-editor-for-edit
    ...
    configure: WARNING: unrecognized options: --with-i-have-misspelled-editor-for-edit
