When the toolchain involved in openscap build does not support C++, the
configure step fails with the following error:
-- Detecting CXX compiler ABI info
-- Detecting CXX compiler ABI info - failed
-- Check for working CXX compiler: /bin/false
-- Check for working CXX compiler: /bin/false - broken
CMake Error at /usr/share/cmake/Modules/CMakeTestCXXCompiler.cmake:73 (message):
The C++ compiler
"/bin/false"
is not able to compile a simple test program.
It fails with the following output:

The openscap project does not contain any C++ file, and so does not need
a C++ capable compiler. Bring the to-be-integrated-upstream patch
enforcing C language in CMakeLists.txt to prevent this build failure.
