corrected ebuild

Newer versions of nvcc and gcc play together nicely.
Comment 1 Felix Janda 2015-11-20 02:56:05 UTC 
(Attachment 417368 [details] has the media-libs/opencv-3.0.0.ebuild with the
lines around the "ewarn" commented out.)

Currently, all versions of nvidia-cuda-toolkit in tree support gcc-4.8
but only nvidia-cuda-toolkit-7.5.18 supports >=gcc-4.9. Therefore I
think it is safe to make open-3.0.0.ebuild also accept gcc-4.8 if the
dependency on nvidia-cuda-toolkit is updated. It is likely not safe to
remove the gcc version detection logic completely because users might
have nvidia-cuda-toolkit-6.5.14, gcc-4.8.4 and gcc-4.9.3 installed and
try to install opencv while gcc-4.9.3 is selected.
