How critical is this fix for 3.5.1?  Will the test-suite fail on new Debian
for everyone, or is it just a Mips issue?

All the missing lines appear in test.log so it seems that stderr is no longer redirected to the *.out-simple along with stdout. This patch fixes this by redirecting stderr to stdout on the perf command.
