Possibly broken CUDA installation on porter

When compiling (e.g.) an empty file:

$ touch t.cu
$ nvcc -c t.cu
/usr/include/c++/10/type_traits:71:52: error: redefinition of ‘constexpr const _Tp std::integral_constant<_Tp, __v>::value’
   71 |   template<typename _Tp, _Tp __v>
      |                                                    ^
/usr/include/c++/10/type_traits:59:29: note: ‘constexpr const _Tp value’ previously declared here
   59 |       static constexpr _Tp                  value = __v;
      |                             ^~~~~

Also, the CUDA admin notes (https://github.com/illinois-scicomp/machine-shop-maintenance/wiki/Admin-notes#cuda) seem to be somewhat incorrect (no /usr/local/cuda*).

Thanks for the report. Just tried, I am not able to reproduce this.

And thanks for the pointer about the admin notes, fixed.
