Raw Blame History

This is a combination of two upstream commits to support building on s390x:
commit 2c01ecec641eb7b4a23d7c0620589ca49bd41697
Author: Neale Ferguson <neale@sinenomine.net>
Date: Mon May 15 16:25:47 2017 -0400
Add s390x support
commit a6861b6adde4d0f5c0c2f9eae87758a348a44419
Author: Samy Al Bahra <sbahra@backtrace.io>
Date: Sat Jun 10 15:36:04 2017 -0400
build/ck.build.s390x: Explicitly define s390x.
This is sticking to the idiom in Concurrency Kit, to safe-guard against
freestanding (or non-Linux) targets with different conventions.
