Reported by @jhux2 - Issue with nvcc_wrapper where it breaks if -O is used to signify optimization.

Example:

$ NVCC_WRAPPER_SHOW_COMMANDS_BEING_RUN=1 /home/sdhammo/git/nvcc-wrapper-nmhamster-github-repo/nvcc_wrapper -o hello-nvcc-wrapper -O hello.cc

Will yield output:

nvcc  -ccbin /home/projects/ppc64le/ibm/xlC/16.1.1/bin/xlC -arch=sm_35  -O    -x cu  hello.cc   -o hello-nvcc-wrapper

with error:

nvcc fatal   : '-x': expected a number
