package/nvidia-driver: build the kernel module
Add option to build the nvidia.ko module. If CUDA is enabled on x86_64,
also build the nvidia-uvm.ko kernel module (for Unified Memory access),
which is required by the CUDA user-land library.
Substancially inspired by the corresponding Gentoo ebuild:
http://sources.gentoo.org/cgi-bin/viewvc.cgi/gentoo-x86/x11-drivers/nvidia-drivers/nvidia-drivers-340.32.ebuild?revision=1.2&view=markup
[Thomas:
- add quotes when using $(TARGET_CC) and other variables, since they
can have spaces in their values
- remove space after opening parenthesis and before closing parenthesis.]

Say 'y' here if you plan on running a program that uses
those private libraries.

+ Build the nvidia.ko kernel module.
+
+ If CUDA support (above) is set, and the target is x86_64, then
+ this will also build the nvidia-uvm.ko kernel module, which
+ provides Unified Memory access to the GPU and CPU memories for
+ CUDA programs.
