Yes, but then please don't compile it in. Otherwise other modules (which make 
sense on a server) build against functions from cfg80211 and *don't* end up with 
a nop-stub - just because the actual implementation was compiled as part of the 
cfg80211 module (but not shipped).

It looks to me like Moritz checked it (I didn't) and they were not available 
for his aws kernel.

Kind regards,
