[llvm-dev] failed to build llvm since 25de7691a0e27c29c8d783a22373cc265571f5e9 on AMD platform

[Brian Cain via llvm-dev]

The host compiler failed to build a sample with '-std=c++11'.  This could
be a simple misconfiguration of your host toolchain, missing libraries,
etc.  Check those cmake error logs to see what in particular weren't wrong.
