+                    Specifies a list of options that, if reported by the
+                    configure script as being invalid, should not generate a
+                    warning during the
+                    <link linkend='ref-tasks-configure'><filename>do_configure</filename></link>
+                    task.
+                    Normally, invalid configure options are simply not passed
+                    to the configure script (e.g. should be removed from
+                    <link linkend='var-EXTRA_OECONF'><filename>EXTRA_OECONF</filename></link>).
+                    However, common options, for example, exist that are passed
+                    to all configure scripts at a class level that might not
+                    be valid for some configure scripts.
+                    It follows that no benefit exists in seeing a warning about
+                    these options.
+                    For these cases, the options are added to
+                    <filename>UNKNOWN_CONFIGURE_WHITELIST</filename>.
