Subject: [PATCH] Toolchain: Fix self-built QEMU crashing on startup on macOS

If the SDL libraries are present on the system, QEMU will attempt to use
that for rendering the UI. This causes a crash when the AArch64 port
starts up with the following message:

> NSWindow drag regions should only be invalidated on the Main Thread!

Fix this by explicitly disabling SDL support.
