I am seeing a couple of new test failures with gcc 6.1.0 on aarch64 in
Release mode. Debug mode works. They work with gcc 8.2.0 in Release
What compiler(s) do the Builbot builders use? Presumably if we use the
same compiler(s) we should see the same testing result. I'm trying to
isolate the problem and it would be good to run a sanity check to get a
baseline. I looked through zorg but it's not obvious to me where
compilers are chosen. The only reference I saw was to some path to 'cc'
and 'CC', which doesn't tell me anything about what 'cc' and 'CC'
Thanks for the help!
