+    depends on EXPERIMENTAL
+    help
+      If you say 'y' here, then the toolchain will also contain the C library
+      optimised for some variants of the selected architecture, besides the
+      default settings.
+      
+      This means the build time of the C library will be in O(nb_variants).
+      
+      The list of variants is dependent on the architecture, and is hard-coded
+      in gcc, so it is not possible to say what variants to support, only
+      whether hard-coded variants should be supported or not.
