The flags used by the project explorer to interrogate the toolchain for
compiler-defined #defines always indicate a C++ file. So, this will
always include a #define for __cplusplus. When editing C code with
the clang code model, this results in extern "C" linkage specifications,
which result in warnings or errors.
The proper fix is described in QTCREATORBUG-11709, but is too big to be
done within the 3.1 timeframe.

This field is used by the generic project manager which passes the
".config" file in it. The advantage is that both the SnapshotUpdater and
the clang code model do not need to do anything smart, but can pass it
directly to the preprocessor.

Do not search the standard system directories for include files, but do
search compiler builtin include directories. To make sure that the
include files for intrinsics are the ones clang can parse, put that
path first on the command-line.
