Indeed that we were able to reproduce and reported that issue as
9000976236 "Segmentation fault during mesa3d build" to our toolchain guys.
Hopefully will be fixed soon.

Well I was trying to reproduce that locally but to no avail.
Indeed I tried to strip everything but "util-linux" from defconfig to save time so
might be that's the reason of my failed attempt.

Still google tells me there's a similar issue with MIPSEL, see
http://autobuild.buildroot.org/results/112/112e8b85783f5aaba42a937a6eb064317615a21b/build-end.log

So I would assume that's not just ARC. Still I'm going to start building full defconfig
from failed build and we'll see if I'll be able to trigger that same issue.
