Subject: When packages fail with --jobs > 1 and the "echo" elog module is not
 enabled, emulate elog's mod_echo module to show the 'error' level messages,
 which should include the important die message. This is implemented by adding
 a private hook inside elog_process() which the scheduler uses to collect
 error messages.
