Help with an s390x build failure

Are there any test s390x instances available for a peon like me to use to diagnose a build failure? Failing that, does anybody with access to an s390x instance have time to help me? The latest bigloo release built successfully on all arches but s390x: https://koji.fedoraproject.org/koji/taskinfo?taskID=20740401 The failure comes after the main binary has been built and linked successfully, but then is executed to compile some Scheme files. The binary is reporting that it was invoked on an empty input file. Thank you, -- Jerry James http://www.jamezone.org/
