[swift-dev] Building swift-3.1-branch from source

[Florian Friedrich]

What version of clang are you using? I’ve had the same problem with clang 3.9 when building on Ubuntu 16.04 on RasPi: https://twitter.com/ffried/status/833985445516165121
Using clang 3.8 worked fine.

I'm actually able to build the 3.1 branch on s390x so I'm wondering if I'm missing some pre-reqs or setting? Any clues would be much appreciated!
