That seems alright as long as you're definitely sure that sdkdir is
not used anywhere by the driver. Looking at nv, it seems that line
comes from the initial autotools addition.

http://cgit.freedesktop.org/xorg/driver/xf86-video-nv/commit/?id=6ea22f19210448605b9a18bf500c33168a77e77c

I'd guess the other drivers have that line for the same reason, and in
that case I'd feel more confident that it's not being used most of the
time.
