This is required since an exec on macOS always has to link against libSystem.dylib. Signed-off-by: Jakub Konka <kubkon@jakubkonka.com>

Status quo in stage1 is that we always link dynamically against libSystem when targeting macOS, no exceptions. This has been working well, and I don't see a reason to make it optional. Hopefully that can simplify your task here |
Awesome, thanks @andrewrk! It's not a biggie ATM, but it's definitely good to know, so thanks for the heads up! |

Ultimately, this will be up to the user to specify they want to link against
libSystemon macOS when generating executables/dynamic libraries; however, since we don't propagate-lflags from main yet, baking in linkage tolibSystemin Mach-O is currently behind a Mach-O property that can be enabled for all generated executables. As far as I can tell, since approximately Mountain Lion, every executable running on macOS is required to link againstlibSystem. Here's a link to discussion about this in LLVM.
