[flang-commits] [flang] [Flang] NFC: Update test to work on Mac (PR #144253)

[Kiran Chandramohan via flang-commits]

https://github.com/kiranchandramohan created https://github.com/llvm/llvm-project/pull/144253

`%flang` expands to `flang -isysroot <SDK location>` in Mac and probably other OS as well. `fc1` is only accepted as the first argument and hence in this case it fails.

Use the `%flang_fc1` option to correctly expand to `flang -fc1 -isysroot <SDK location>`.
