[build bug] CONFIG_MAC80211=m && CONFIG_RT2X00=y

[Ingo Molnar]

hi,

FYI, i triggered a build failure and have the hack below in -tip. Did 
not have time to track down why the build fails exactly, so i disabled 
the driver as a quick hack. Would be glad to test any fix patch.

This could perhaps have been caused by the change to menuconfig,

Does changing bool to tristate help?
Because the depends are all properly set, so it should not be possible
to set rt2x00 to compiled-in while mac80211 is a module..
