Subject: Do not output to stderr during the build.
X-Git-Url: https://git.sesse.net/?p=stockfish;a=commitdiff_plain;h=0e89d6e7546d26a19a108d047b489d9ba6f7970c;hp=a8330d5c3bfeb4c9d5c55083223792e0989bb9c6

Do not output to stderr during the build.

To help with debugging, the worker sends the output of
stderr (suitable truncated) to the action log on the
server, in case a build fails. For this to work it is
important that there is no spurious output to stderr.

No functional change
