Update ebuild to support gcc-4.9

According to the debian bug here:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=757961 ,
the nvidia cuda toolkit supports gcc-4.9 since version 5.5. It just isn't reflected yet in host_config.h.

I have uploaded a modified ebuild and a patch to change host_config.h to my overlay "seden" for testing.

The patch to the ebuild and to the file will be added here.

However, with the ebuild from my overlay it can be tested whether there are regressions that were not found by the Debian team or not.

Sadly I will stick to what upstream says.

And what does upstream say?

Nothing on : http://docs.nvidia.com/cuda/cuda-getting-started-guide-for-linux
Nothing here : http://docs.nvidia.com/cuda/cuda-toolkit-release-notes/
And nothing in here: (of course) http://developer.download.nvidia.com/compute/cuda/6_5/rel/docs/CUDA_Toolkit_Release_Notes.pdf

The only hint is the preprocessor macro in host_config.h, and that was overridden often before without ill effect.

However, if someone wants to use gcc-4.9+ on a cuda enabled system, they can go with the ebuild from my overlay until this one single digit in host_config.h has been changed. ;)
