Some versions of GNU gold are known to produce broken code with --fix-cortex-a53-843419 as explained in this bug: https://sourceware.org/bugzilla/show_bug.cgi?id=21491 If ARM64_ERRATUM_843419 is disabled and we're using GNU gold, pass --no-fix-cortex-a53-843419 to the linker to ensure the erratum fix is not used even if the linker is configured to enable it by default.
