That comes from:

if test x$enable_symvers = xyes ; then
  if test $enable_shared = no || test "x$LD" = x || test x$gcc_no_link = xyes;
then
    enable_symvers=no
  else
    if test $with_gnu_ld = yes ; then
      case ${target_os} in
        hpux*)
          enable_symvers=no ;;
        *)
          enable_symvers=gnu ;;
      esac
