Tests failing on s390x

The following tests are failing in Debian and Ubuntu infrastructure on s390x architecture:

FWIW I ran the tests from the current master branch in a s390x VM and I got the same failures.

/cc: @makeable, @stakach: could you perhaps take a look at this?

I don't expect a different behavior on s390x architecture, for example, HttpParser::Instance#initialize #type should indeed default to :both and probably not :request. Likewise, I don't understand why it'd return false if the "Upgrade header" is already set.

For other architectures, this works fine, maybe we're missing something on s390x? or is there something wrong with tests in general sense, maybe(!?), 'cause I don't see an obvious reason for them to fail here?

Thanks in advance! 🙈

Oh well, I hope the problem isn't due to native extensions on s390x. I've seen sometimes those to be a problem, but hoping this wouldn't be it here as well (or is it!?) 🙈
