Not sure if we need it. I was trying to fit within what was there and it felt weird to set the TARGET_SYSTEM_NAME to iOS when I know it should be Darwin

Oh, I am misreading what is happening. We set AOT_TARGET_TRIPLE from the outside. And then that sets TARGET_SYSTEM_NAME and then TARGET_SYSTEM_NAME is used to set other target properties. So it's not redundant. The triple is the source of truth.

It's unfortunate that we use the same triple for ios and mac. Did we do that in mono/mono, too? @vargaz ?

We has no cross compiler to osx previously, probably just used the normal host mono. If we need it, it should use a separate triple.

Is there anything you would suggest?

Something like x86_64-apple-macos

according to https://reviews.llvm.org/D40998 they use x86_64-apple-macosx (note the x at the end) for clang's -target but if I understand correctly we're not passing the triple down to clang here so this is just for us?

IOS_DEFINES sounds a bit weird here if we're using it for macOS too. We should probably rename it to APPLE_DEFINES. Also if we're using a different AOT_TARGET_TRIPLE for macOS then we need to also add the case for x86_64 here that is covered by the iOS case on L149 now.
