I've had some ideas about how to squirrel output back through the buildbot,
etc - but would take more time/investigation than I'm likely to devote to
the task any time soon, unfortunately.

In the short term/interim, you might be able to "REQUIRES: shell" and use
"tee" the output to a temp file, then run FileCheck on the temp file. That
way it should dump the output, then show FileCheck results after that.
