Makefile needs to select correct gcc compiler #72

Plainly invoking nvcc isn't guaranteed to work:

nvcc -ptx -gencode=arch=compute_20,code=sm_20 utils.cu
nvcc warning : The 'compute_20', 'sm_20', and 'sm_21' architectures are deprecated, and may be removed in a future release (Use -Wno-deprecated-gpu-targets to suppress warning).
In file included from /opt/cuda/bin/..//include/cuda_runtime.h:78:0,

 #error -- unsupported GNU version! gcc versions later than 5 are not supported!
  ^~~~~
Makefile:15: recipe for target 'utils.ptx' failed
make: *** [utils.ptx] Error 1

Luckily, I've already implemented such a mechanism as part of CUDAdrv. Maybe we should move this functionality, and the entire compilation example, over to CUDArt (since CUDAdrv doesn't require nvcc to be installed except for that example)?

I guess this is noe fixed
