[llvm-dev] failing bootstrap: C++11 or greater is required but the compiler does not support c++11

[Kostya Serebryany via llvm-dev]

started with
http://lab.llvm.org:8011/builders/sanitizer-x86_64-linux-fuzzer/builds/1380
(Fri Dec 9 18:42:04 2016)
The previous one (Fri Dec 9 17:41:56 2016) was fine.
There was just one revision between these runs (mine), but reverting it
does not help.
Maybe an update in Ubuntu 14.04 broke this?
