I don't think this will work. The issue is not symlinks but the fact that we
change directories during the script.

ls -1 $(pwd)/build_packages

may work

  Right, but readlink -f reports full path.
  I think readlink -f is more reliable then the result of ls.
  Check the rest of scripts in src/scripts - they all use readlink -f.
