The failed item was;

Command `/checkout/obj/build/x86_64-unknown-linux-gnu/stage1-tools-bin/rustbook test /checkout/src/doc/reference` failed with exit code 101

// More output

ERROR: Tool `reference` has regressed from test-pass to test-fail during beta week.

Which, unless I'm mistaken, is not caused by these changes?
