Jonas Maebe 82d92dbf50 * call seterrno instead of manually handling the setting setting the errno
threadvar (and having to deal with differences between the ELFv1 and ELFv2
    ABIs regarding indirect function calls, + future ability to have the
    compiler generate PIC for those routines)
   o includes workaround for lack of linkage area size allocation in current
     released PPC64 versions, remove after 3.0.2 has been released
