+LLVM 15 gates its Mach-O linker behaviour on `CMAKE_SYSTEM_NAME MATCHES "Darwin"`,
+which is false when cross-compiling for iOS/visionOS (CMAKE_SYSTEM_NAME is "iOS" /
+"visionOS"). The build then falls through to the ELF/COFF paths and passes flags
+Apple's ld rejects. Use `APPLE`, which is true for every Apple platform.
+
+Fixed upstream after 15.x; drop this patch when moving to a newer LLVM.
+
+  1. add_llvm_symbol_exports() fell through to the Windows branch and handed a
+     .def file to ld:
+       ld: unknown file type in '.../LLVMHello.def'
+
+  2. -Wl,-z,defs is ELF-only and was not excluded for iOS:
+       ld: unknown options: -z
+
+  3. add_link_opts() skipped -Wl,-dead_strip, so non-Debug builds silently lost
+     dead stripping that the macOS build of the same sources already gets.
+     Not a build failure, just larger output.
