package/openscap: add patch to enforce project as C project

Browse Source 
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.

Subject: [PATCH] Set project as C project in CMakeLists.txt
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The openscap tool has been recently integrated in the buildroot build
system ([1]), which makes the openscap tool buildable for a wide variety
or architectures/OSes, with a wide variety of _compilers_. And so when
such compilers are not supporting C++ projects (as it is the case with a
default buildroot toolchain), the build breaks on the following error
(see [2] for an example):
-- 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:

openscap does not have any C++ code to build, so restricting builds to
toolchains supporting C++ is overconstraining, the configuration step
should rather not try to check C++ support.
Enforce the project as a C project in CMakeLists.txt to make sure not to
test C++ features on the used toolchain.
