Some targets, such as `aarch64-pc-windows-msvc`, always require that Frame Pointer be reserved even when `-fomit-frame-pointer` is provided, thus it is always valid to use `-pg` on those targets.

This test didn't take these targets into account; thus it was failing on Arm64 Windows host machines.

The fix is to explicitly set a target that doesn't require Frame Pointers reservation.
