Error: Util aarch64-apple-darwin19-strip not found, switching to external linking

This is the same problem as this closed issue (but not fixed issue):

#604

I'm trying in Linux (lubuntu 24) to cross compile a dynamic library for aarch64, Darwin. I have numerous times compiled successfully my other program to aarch64, Darwin using a fpcupdeluxe installation, but it doesn't work for this simple dynamic library. This is the error I get:

Hint: (11031) End of reading config file /home/h/fpcupdeluxe/fpc/bin/x86_64-linux/fpc.cfg

I have installed clang since it was first missing.
And this is the simple source:

library test;
{$mode objfpc} {$H+}

uses
  // needed for UpperCase
  SysUtils;

// library subroutine
function cvtString(strIn : string) : PChar; cdecl;
  begin
    cvtString := PChar(UpperCase(strIn));
  end;

// exported subroutine(s)
exports
  cvtString;
end.

Any idea how to get this fixed?
