Mark,
When it calls the C compiler it prints Preprocess stderr before filtering:No supported cpu target is set, CRAY_CPU_TARGET=x86-64 will be used. Load a valid targeting module or set CRAY_CPU_TARGET the C compiler is outputting its message on stderr and that is triggering the configure failure. Since PETSc does not know this is a harmless error message. I will update the filter code to ignore this "error message" but you should just set that environmental variable before you run configure or use the modules in a different way.
