To allow building MongoDB on Linux s390x:

src/third_party/wiredtiger/src/support/global.c contains a check against big-endian systems around line 45; that needs to be removed.

Andrew Morrow, I'm hesitant to merge this patch until big-endian systems work, we'll likely be making new standalone releases before that's true?

Comment by Andrew Morrow [ 19/Dec/15 ]

Keith Bostic - That is definitely a valid concern, and I expect some of the same push back on the fix for SERVER-21821, for similar reasons. Lets discuss next week and come up with a plan. As I suggested in the code review for SERVER-21821 perhaps a build configuration flag (--enable-experimental-big-endian-support) or runtime flag would be a good compromise. I do want us to do something though so that every developer working on big-endian support doesn't need to manually apply this patch just to get started. I figured I'd start with the simplest thing first, and we can iterate from there.

Andrew Morrow, happy to talk it over, but if there are multiple people working on big-endian changes, then let's just merge and move on. The likelihood of a problem in the field is close to non-existent, and I'm not prepared to cause you/us any pain to deal with the possibility.
