The return value of `clang_getClangVersion()` is a CXString structure. Depending on the architecture the structure can be returned on the stack or via a register. When assuming it is a `ctypes.c_char_p`, the ctypes FFI call will segfault upon return on armhf due to not properly handling how the architecture is returning the data. Properly setting the return type for `clang_getClangVersion()` will avoid the segfault. Signed-off-by: Kienan Stewart <kstewart@efficios.com>
