For OpenMP target offload, there are a few default OMP_FLAGS_OFFLOAD_<COMPILER?>_<VENDOR? settings, which may work for some systems e.g. OLCF Frontier. However, setting this flag tuple doesn't currently set OMP_TARGET_GPU, so the application doesn't actually compile for offload.
This fix defines OMP_TARGET_GPU whenever OMP_FLAGS_OFFLOAD_<COMPILER?>_<VENDOR? is defined. With this fix, BabelStream correctly builds for OLCF Frontier with:
