Ok, apparently $(PWD) is not available on all shells?

Well, there's not much I can do for now. r92su is a unofficial module.

insmod doesn't load any dependent modules.
(In this case all that's missing is: cfg80211 - the new
makefile should take care of that)

Ah, unload r8712u before loading r92su [else, r92su won't control the device]. 

modprobe -r r8712u

If r92su works and you want to stick with it for the time, you can
blacklist r8712u. AFAICT, you just have to follow the instruction at
<https://docs.fedoraproject.org/en-US/Fedora/16/html/Installation_Guide/rescuemode_drivers-blacklisting.html>
