Ah, yes.  I also had CCACHE_PREFIX set:

CCACHE_PREFIX=distcc

I don't have any distcc servers enabled, which for everything else
causes a fallback to localhost, but apparently this is what was causing
the problem; unsetting this environment variable was also enough to
cause the nvidia modules to successfully compile.

I'm not sure why it makes a different to the nvidia module.  I've built
kernels with this set, and it doesn't seem to make a difference....
(the reason why I turn it on even when I have no distcc cluster
available is that having this variable set changes how ccache calculates
the hash for its cache, so when I *do* have a distcc cluster available,
I don't end up invalidating everything in my ccache cache).
