I was curious about this myself recently. I think there is
a lack of detail in the nvidia kmod build logs because they
don't pass V=1 to the make command. This results in nice,
quiet build output. But for package builds it's preferable
to see the options used. I've submitted a patch to
rpmfusion for the nvidia-kmod package:
https://bugzilla.rpmfusion.org/4800
If that's accepted, I or someone else can work on adding the
same V=1 to the make command for the other nvidia-*-kmod
packages.
The difference with and without V=1 is quite a lot.
Without V=1:

With V=1:
https://paste.fedoraproject.org/paste/jPkevkTHxq42boCeS5okyA
And to keep it more relevant to this thread, with the
verbose make I can see that -DRETPOLINE is used when
building the nvidia kmod on my f26 system.
Thanks for sending me on a fun hunt Ed. :)
