That was not the cause of the buildbot reporting failure, but it IS
noisy.  I suspect it is because your buildbot is running in an
environment with SIGPIPE ignored (and sadly, there is NO way from shell
to turn SIGPIPE back to normal if the shell inherits it as ignored).
Since this noise is occurring in a stock 'make syntax-check' from
gnulib, we ought to patch gnulib to work around noisy tools that don't
tolerate SIGPIPE being ignored.
