With this patch, building release started to fail with the following error:

My cmake configuration contains these libomptarget-related  (because we have various GPU gens in our cluster):

  -DCLANG_OPENMP_NVPTX_DEFAULT_ARCH=sm_70 \
  -DLIBOMPTARGET_ENABLE_DEBUG=on \
  -DLIBOMPTARGET_NVPTX_ENABLE_BCLIB=true \
  -DLIBOMPTARGET_NVPTX_AUTODETECT_COMPUTE_CAPABILITY=OFF \
  -DLIBOMPTARGET_NVPTX_COMPUTE_CAPABILITIES="35;60;70" \
