A C++11 compiler is required:
  ISO C++11 compiler
  Necessary to bootstrap GCC.  GCC 4.8.3 or newer has sufficient
  support for used C++11 features, with earlier GCC versions you
  might run into implementation bugs.

That isn't the host.  The target triple is cpu-vendor-os.  "unknown"
is pretty normal here, and doesn't usually make a difference.  If you
do use something here you will have to use the same thing for all tools,
so it is easier to just use the detected thing usually.
