[Libclc-dev] [PATCH] Make libclc link if llvm was built with --enable-libcpp --enable-cxx11

[Jeroen Ketema]

If llvm was built with

   --enable-libcpp --enable-cxx11

then any C++ code compiled and linked against LLVM
needs to include

   -stdlib=libc++ -std=c++11

Unfortunately, these just occur in --cxxflags of
llvm-config and not in --ldflags. Hence, the flags
are not passed when linking prepare-builtins. As a
work around pass all --cxxflags at the linking stage.
