Compiler is CLANG/LLVM, target arch is amd64, in that case, an oldish IvyBridge, but it
fails the same way on Haswell as well. 64bit.

For buildworld, I use in /etc/src.conf this since an eternity (measured in the metrik of
11-CURRENT):

CPUTYPE?=               native
#
CFLAGS+=                -O3 -pipe
# for the kernel
COPTFLAGS+=             -O3 -pipe
#
CXXFLAGS+=              -std=c++11


As it has been earlier stated, there is no -std=c++11 visible in the cc options, only
-std=gnu99.

The compiler gives the right suggestion itself, but someone should fix and commit ...

Regards,

Oliver
