[Mvapich-discuss] Build Failure with NVHPC 23.3

[Korzennik, Sylvain]

I ran into the exact same problem - unclear to me why config w/ NVIDIA 23.x
turns on "supports fortran 2008" and then fails miserably, while NVIDIA
22.x compilers did not.
Also, the config adds -rdynamic that is not supported by NVIDIA's compilers.
    Cheers,
      Sylvain
