Thanks to both of you.
That works very well.  However, the base64 output in my first log was
corrupt, due to some asynchronous output (stderr about job completion)
that was emitted in the middle of the big base64 block.
Adding the "sync; sleep 10" part below should avoid that in the future:

Instead of the usual %check rule,

  make %{?_smp_mflags} check

I now use this, when needed:

  # After a failed make check, tar up, compress and base64-encode all results
  # The "sync; sleep 10" should ensure that no async output is printed
  # in the middle of the big base64 block.
  make %{?_smp_mflags} check \
    || { st=$?; tar cf - . | xz -9 | base64; sync; sleep 10; exit $st; }
