build: Error out on missing AX_CXX_COMPILE_STDCXX_11
A missing AX_CXX_COMPILE_STDCXX_11 at autoreconf time will only trigger
a non-fatal "command not found" when configure runs, but then
compilation will unexpectedly fail unless -std=c++11 is added to the
CXXFLAGS.
This commit makes sure we error out at autoreconf time when the macro
is unknown.
