Subject: [PATCH] CMakeLists.txt: fix build without C++

Specify that AvroC is a C project and remove tests_cpp.cpp to avoid the
following build failure if a C++ compiler is not found:

CMake Error at CMakeLists.txt:20 (project):
  The CMAKE_CXX_COMPILER:

    /home/naourr/work/instance-2/output-1/host/bin/microblazeel-buildroot-linux-uclibc-g++

  is not a full path to an existing compiler tool.

  Tell CMake where to find the compiler by setting either the environment
  variable "CXX" or the CMake cache entry CMAKE_CXX_COMPILER to the full path
  to the compiler, or to the compiler name if it is in the PATH.

Fixes:
