4.17 branch is no longer compilable from scratch in Linux

If I get following commit, I can compile UE4 on Linux 4.17 branch all good:

commit 93f5fdab7929916beadce2c5a16fd1b82a2dd532
Author: Dan Oconnor <Dan.OConnor@epicgames.com>
Date:   Tue Aug 15 16:54:11 2017 -0400

However if I get this latest 4.17 branch and compile from scratch then I get “UBT Error” without any error messages indicating the problem:

commit c9d5c4e649f3ae339fc99e512dae54b430b08816
Author: buildmachine <unrealbot@epicgames.com>
Date:   Tue Aug 29 03:09:19 2017 -0400

Error message:

Total build time: 3031.65 seconds (Local executor: 0.00 seconds)
Makefile:183: recipe for target 'UE4Editor' failed
make: *** [UE4Editor] Error 5

Just got latest again and looks like later commit has fixed the issue.
