There's a typo in the link, it should end with '.xz' not '.xy':
https://ci.linaro.org/job/tcwg_gnu_cross_check_gcc--master-aarch64-build/1215/artifact/artifacts/08-build_abe-stage2/console.log.xz


Anyway we now extract the configure / make commands, the relevant one is at
step 08-build_abe-stage2 in
