    config: update and relocate AC_DEFINE_DIR macro
    
    Remove deprecated acinclude.m4 macro container file
    Use separate macro files as per autoconf recommendation
    Use the latest macro from GNU (ax) which replaces
    the non-gnu version (ac)
    This preserves the Autoconf macro AC namespace.
