As the patch stands --cross-prefix="" works but I like having the
--enable-cross-compile option because it's more clear of the intention
(in logs and such). I've been struggling to come up with a concise

Just to be clear, you're in favor of removing the
--enable-cross-compile option? I can do that if others agree but I'm

No, because if you build on a macOS 11 host but try to run it on macOS
10.15 then it will crash.

Hi, I'm wondering what the progress is for this patch set and the iOS
support one? I know 5.2 is frozen, so will this be considered for 6.0?
Apple Silicon Macs are out now and a few people are asking about QEMU
support :)

Sorry, are you asking for a review from me? I don’t know if I’m
qualified to review the other patches but I did review the iOS patch.

The iOS toolchain does not use the host prefix naming convention. So we need
to enable cross-compile options while allowing the PREFIX to be blank.

Some hosts (iOS) have a sandboxed filesystem and do not provide low-level
APIs for interfacing with host block devices.

macOS 11/iOS 14 added preadv/pwritev APIs. Due to weak linking, configure
will succeed with CONFIG_PREADV even when targeting a lower OS version. We
therefore need to check at run time if we can actually use these APIs.
