as it's done for other AArch64 targets although the linker (GCC) _may_ be configured to apply the fix by default it's preferred to have rustc pass the flag to the linker to ensure the mitigation is always applied for example, the Arm GNU toolchain does _not_ enable the errata mitigation by default (checked version: 13.3.Rel1) see issue 118095 for background information
