ampere build issue

Building on perlmutter, which has A100s.

For sm_80 we pass ampere as VTKm_CUDA_Architecture, which results in:

Here is my config:

    elseif(VTKm_CUDA_Architecture STREQUAL "ampere")
      set(arch_flags --generate-code=arch=compute_80,code=sm_80)
      set(arch_flags --generate-code=arch=compute_86,code=sm_86)

This seems to result in libs that only have sm_86

cuobjdump libvtkm_cont-1.7.a 

...
...

Fatbin elf code:
================
arch = sm_86
code version = [1,7]
producer = <unknown>
host = linux
compile_size = 64bit

We need sm_80 b/c sm_86 executable won't run on A100.

(I tested example hello world with both sm_80 and sm_86, and only the sm_80 runs)
