gnu: linux-libre: Disable CONFIG_DEBUG_INFO and turn off nvidiafb module.
Disabling CONFIG_DEBUG_INFO so that local builds aren't so enormous.
Also turning off nvidiafb module based on a bug report I received.
Nouveau has its own framebuffer device and it looks like they conflict
if you load both.
* gnu/packages/linux-libre-x86_64.conf: Comment out CONFIG_FB_NVIDIA,
and remove related items. Comment out CONFIG_DEBUG_INFO.
* gnu/packages/linux-libre-i686.conf: Likewise.
