Native CPU is not reported on Raspbian

[kryptan]

Executing rustc --print target-cpus or rustc -Ctarget-cpu=help on Raspberry Pi 4 prints the following:

Available CPUs for this target:
    arm1020e
    arm1020t
    arm1022e
    ...

In contrast, executing the same command on Windows or Ubuntu on x86-64 also prints native CPU:

Available CPUs for this target:
    native         - Select the CPU of the current host (currently skylake).
    alderlake
    amdfam10
    athlon
    ...

In source code there is check for cross compilation. Native CPU is only printed when not cross compiling:

  printf("Available CPUs for this target:\n");
  if (HostArch == TargetArch) {
    const StringRef HostCPU = sys::getHostCPUName();
    printf("    %-*s - Select the CPU of the current host (currently %.*s).\n",
      MaxCPULen, "native", (int)HostCPU.size(), HostCPU.data());
  }

However I'm not cross compiling. I'm using rust installed from rustup and don't have any additional targets installed.

rustup show:

Is this related to what I hit in rust-rse/reed-solomon-erasure#94 ?

on a coretex-a57 SoftIron overdrive1000 from 2016 ...
