>Description:

The sparc test runs on the TNF testbed are failing with a timeout
since December 11.  They appear to hang while running the
lib/libossaudio/t_ossaudio test.

The problem started during the period of build breakage that began
with the commit of that test:

  2020.12.11.12.29.27 nia src/tests/lib/Makefile 1.34
  2020.12.11.12.29.28 nia src/tests/lib/libossaudio/Makefile 1.1
  2020.12.11.12.29.28 nia src/tests/lib/libossaudio/t_ossaudio.c 1.1

Presumably the new test has exposed an existing bug in the sparc audio code.
