[PATCH] fix menuconfig help for choice menus

[Mitch Adair]

Menuconfig currently doesn't show the help texts that go along with config
options inside a choice menu.  (A good example is the "Processor family"
submenu - none of the per-processor help texts show up.)

The following patch fixes this - menuconfig now shows the help text for
the config option under the cursor.
