cc1plus: error: unrecognized command line option "-std=c++11"
commit 12187550f9c248e72ed8848e96da8f29f1e3a713
Author: Emil Velikov <emil.veli...@collabora.com>

configure: add CXX11_CXXFLAGS to LLVM_CXXFLAGS
Seemingly with LLVM7 and GCC 5.0, the former won't properly advertise
-std=c++11 and the latter will choke.
dd this temporary workaround, otherwise we'll get errors like:

requires compiler and library support for the ISO C++ 2011 standard. This
support must be enabled with the -std=c++11 or -std=gnu++11 compiler options.
