[flang-commits] [flang] [flang] Fix Driver/do_concurrent_to_omp_cli.f90 test not to use runtime (PR #135485)

[Michał Górny via flang-commits]

https://github.com/mgorny created https://github.com/llvm/llvm-project/pull/135485

Fix Flang invocation in `Driver/do_concurrent_to_omp_cli.f90` test to run compilation step only, to fix testing when building with `-DFLANG_INCLUDE_RUNTIME=OFF`.  The test is only concerned with warning being emitted by the compiler, so there is no need to link the resulting executable.
