Implement the -mfix-cortex-a53-843419 and -mno-fix-cortex-a53-843419 options, which have been introduced to GCC to allow the user to control the workaround for the erratum. If the option is enabled (which is the default, unchanged by this patch), Clang passes --fix-cortex-a53-843419 to the linker when it cannot ensure that the target is not a Cortex A53, otherwise it doesn't. See https://gcc.gnu.org/onlinedocs/gcc/AArch64-Options.html#index-mfix-cortex-a53-843419 for information on the GCC options.
