Such an insight is offered by an older commit:

  commit 642699970e75580e0f11f5786302082e25d8f49c

      Use append mode to capture parallel test output.

      * tests/lisp8.test: Use append mode for output from `make -j',
      to avoid dropped lines.
      * tests/parallel-tests3.test: Likewise.

I've verified (with the help of the attached script) that such an issue
is indeed present on the affected systems (my Debian box and the Fedora
ppc64 system offered by the GCC compile farm), and I've pushed the
attached patch to fix it.  I'm thus closing this bug report.

Regards,
  Stefano
