----------------
I think that GNU in this case might be a bit misleading. These linker invocations are defined in almost completely independent toolchains: [[ https://github.com/llvm/llvm-project/blob/b9a7dea9171416a998e4fa3333fb9f76baa167b8/clang/lib/Driver/ToolChains/Darwin.h#L33-L47 | MachOTool ]], [[ https://github.com/llvm/llvm-project/blob/b9a7dea9171416a998e4fa3333fb9f76baa167b8/clang/lib/Driver/ToolChains/Gnu.h#L40-L51 | gnutools ]].

I't be inclined to try this instead:
```
! RUN: %flang -### -flang-experimental-exec -target ppc64le-linux-gnu %S/Inputs/hello.f90 2>&1 | FileCheck %s --check-prefixes=CHECK,GNU
! RUN: %flang -### -flang-experimental-exec -target aarch64-apple-darwin %S/Inputs/hello.f90 2>&1 | FileCheck %s --check-prefixes=CHECK,DARWIN
! RUN: %flang -### -flang-experimental-exec -target x86_64-windows-gnu %S/Inputs/hello.f90 2>&1 | FileCheck %s --check-prefixes=CHECK,MINGW
! RUN: %flang -### -flang-experimental-exec -target aarch64-windows-msvc %S/Inputs/hello.f90 2>&1 | FileCheck %s --check-prefixes=CHECK,MSVC
```

This will lead to more duplication, but would clarify things a bit.
