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

[Vivian Kong]

I actually have a question regarding build as well.  I haven't been able to
build 3.1 branch from source on Ubuntu 16.04 x86_64.  I hit this error:

./swift/utils/build-script -r

...

I saw https://bugs.swift.org/browse/SR-4147 opened for the master branch
(and the workaround is to move to Ubuntu 16.04).  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!

Yes it works!  Thanks!
