Subject: fix stack protector gcc spewage
From: Arjan van de Ven <arjan@xxxxxxxxxxxxxxx>
installed gcc 4.0.2 and reproduced your warning.. patch below fixes it for
me.
divert stderr to /dev/null in the stackprotector check; we're only
interested in the stdout assembly, while gcc's that don't grok some of the
options we provide would spew to stderr...
