setup.py and GCC version

[jlgao2]

Thanks for making this repository public!

I was setting this up today and I had some issues building the cuda extensions when I use gcc8.1.0, however when I used gcc 6.1.0 I was able to build successfully.

The error I received is shown below.

I have not tried gcc8. 1, maybe it's because of the compatible issue. I do not know how to resolve the error. Maybe this could provide some info:　pytorch/vision#1893

gcc 5~gcc 7 is OK.
